Mozilla staff (including speakers) who are interested in attending FOSDEM must book their own travel and hotel.

All sponsored Mozillians will be staying at the Novotel Grand Place in shared twin rooms. An email containing detailed information on their hotel will be sent to all sponsored participants.

Mozilla DevRoom

Every year Mozilla developers and contributors have a dedicated room (ie. Mozilla DevRoom) in which to hold talks and sessions.

This year, Mozilla will have:

  • room U.218A (next to Chavanne) on Saturday from 11:00 to 19:00
  • 363 seats;
  • power (C/E plugs)
  • a video projector (VGA);

The schedule is now finalized, check the schedule on the official FOSDEM page where the selected talks are beginning to appear. Speakers have been contacted already.

Mozilla Booth

There will be a booth manned by Mozilla volunteers in the main conference building. The goal is three-fold:

  1. to evangelize and answer questions
  2. to recruit new volunteers;
  3. distribute merchandise.

If you would like to volunteer to help man the booth, make sure to sign-up in the chart below. In general, if you notice that someone has been at the stand for a while, please don't hesitate to switch places with him/her! Also, please help to keep the place clean and tidy!

Where is it located?

The Mozilla Booth is located on the ground floor of Building K next to the main parking, and close to the main Infodesk. See this map:

Food, Beverages, and Saturday evening party

Breakfast will be served for sponsored Mozillians staying in one of the hotels Mozilla has secured for the event.

Any other food or drink expenses (including room service and in-room minibar charges and lunch at FOSDEM) are at the expense of the Mozillian.

Friday Beer Event

As every year, there will be a FOSDEM beer event on Friday night before FOSDEM. We'll be distributing a limited amount of free drink tokens starting at 6PM, so look out for them :)

Warning: don't forget to read the "A note of caution" part of

Saturday night Party

Historically, a dinner for Mozillians has often been organised on the Saturday night of FOSDEM. For the last couple of years though, Mozillians are encouraged to meet and dine with folks from other open projects. Please watch this space for suggestions.

That said, we will have a Party from 20:00 (8pm) at Café-Brasserie À la Mort subite, Rue Montagne-aux-Herbes Potagères 7, B-1000 Bruxelles (Google, OpenStreetMap). If you come from the Novotel, you can just walk through the beautiful Galeries Royales St Hubert to get there.

Since this is an open event, don't hesitate to invite people you met at Fosdem.

NB: the room can fit a maximum of 80 people and will be open on a first come first served basis.

As with the beer event, Mozilla Reps will be there to hand you "free beer" tickets (33cl). It should be possible to eat a few small dishes there as well (salads, tartines and omelettes).

Getting Around in Brussels (MAP)

A practical Google map is available with all the relevant spots for Mozillians during their stay in Brussels.

Traveling by air to Brussels

Brussels Airport

…the airport is less than 20 minutes from the city centre. From 6am till nearly midnight, the AIRPORT CITY EXPRESS train brings you to Midi, Central and North stations four times per hour. A one-way ticket costs 7.80 €. The city express train is located in the basement (level -1) of the terminal building itself.

Airport to Brussels.gif

There is also a Bus service (Airport Line 12 or 21) but it doesn't go straight to the hotel. If you take that bus, get off at Schuman and take the metro from there to Gare Centrale. The cost is 4.00 € if you buy it at the airport bus station (platform C) or 6.00 € in the bus.

Brussels South Charleroi Airport

Some low-cost flights (Ryanair, Wizzair, …) are operated from there. It is approximately one hour away from the city centre. A shuttle bus (1 hour, €13) will bring you from there to Brussels South Railway station. For your return flight, it is recommended that you take this shuttle bus 3 hours prior departure.

Traveling by train to Brussels

If you are traveling by train to Brussels, it is best for you to get off at the Central Station stop.

Most High-speed trains (TGV, Thalys, Eurostar, ICE) stop at Brussels South (Gare du Midi) instead. From there, you can either find a local train to Central Station, or take the Tramway/Metro (line 3 or 4 to De Brouckère, then metro line 1 or 5 to Gare Centrale).


Most Mozilla speakers and staff will be staying at the Novotel Brussels Grand Place.

  • Information how to reach your hotel from Central station is available here

Here are the hotel details:

Novotel Brussels off Grand'Place
Rue du Marché Aux Herbes 120
Tel:  (+32)2/5143333
Fax:  (+32)2/5117723
Nearest metro stop: Gare Centrale/Centraal Station
See website here

Warning: there is another Novotel called Novotel Brussels Centre Tour Noire a few hundred meters away (near De Brouckère). It is not the same hotel but is equally good and is at walking distance from Novotel Grand Place.

Other hotels in the neighborhood

There are many hotels around the Central station, and in the city center in general.

You may try:

Hotel discounts

A number of hotels in Brussels offer a discount to FOSDEM visitors. See

Other accommodation options

Other great accommodation options exist in Brussels. There are local residents renting couches and private rooms for as little as $30. Also some have reviews.

Coworking options

Arriving early or leaving late and need a nice place to work? The Betagroup Coworking offers to host Fosdem attendees for free on Friday and Monday (9am to 6pm).

Please see details and signup info here: Space is limited and signup will be disabled when the limit is reached.

Don't hesitate to ask Ramón for options if you'd like to stay longer.

WiFi and mobile data

At Fosdem

At FOSDEM, a FREE WiFi network called "FOSDEM" will be very "strong" and there should not be any ambiguity about which network to use. Most 802.11 stacks will likely do the Right Thing[tm] automatically. :-)


There should be Free Wi-Fi at least in the lobby, and possibly in your room. Ask the reception if unsure so you don't get charged for this.

SIM cards/Mobile Data

If you have a GSM-compatible phone and need data connectivity (EDGE/3G) without paying prohibitive roaming charges, you can buy a prepaid SIM card with a data plan in most mobile phone shops, including some in the Airport arrival terminal.

Here are a couple of plans that you may find interesting:

  • BASE: 10€ prepaid card with 5€ top-up (100MB) or 10€ top-up (1000MB)
  • Belgacom/Proximus: 15€ Pay&Go Max prepaid card (250MB included)

Getting from the Hotel/Central Station to FOSDEM

It takes about 35 min from downtown Brussels to FOSDEM by public bus.

From station GARE CENTRALE, take Bus 71 traveling towards DELTA. Get out at the station ULB (22 mins, 14 stops). From there it's a few hundred meters footwalk. The total travel takes about 35 minutes.

Google transit will give you good Public transport directions. If you have a mobile data plan (beware of roaming charges) or are connected to a wifi network, you can also check for waiting times and vehicle positions on or with the Android STIB application.

Useful tip: If you are waiting in the cold at ULB for a bus to get back to the city center (towards De Brouckère) and it doesn't come or you fear it will be too crowded, you may want to take it in the other direction instead (to Delta, a few stops away). Delta is actually a metro station on line 5, which also goes to Gare centrale and De Brouckère.

A detailed map of the ULB campus and of the FOSDEM entrance, as well as detailed instructions on how to get there by public transportation can be found here:

Leaving FOSDEM to leave Brussels

From Sunday afternoon till Sunday evening, FOSDEM will provide free transportation by bus from the conference site (ULB Campus Solbosch) to the Brussels-South railway station which has the best connections to Brussels Airport and neighboring countries.
