Changes

15min walk from the office. Great location, great hotel. Free yoga class on Thursdays, make their own coconut water. Delicious food (local and made from scrap) and drinks. Rooms range from "Cozy" (very tiny but beautiful and has everything you need) to larger scale. More hipster vibe. Very different from your usual hotel. It's an experience in itself.
