Fauna is a great hotel: ecologically friendly design with great use of public areas (only issue maybe the lack of an elevator, so if you have ability issues it may not be the best). The restaurant has top-notch dishes and cocktails. It is also set on their top floor, with a terrace that has great views of the city below. If you walk by the hotel, in their main street, it is hard to imagine how spacious and cool the hotel and restaurant are inside.
Most of all, I was impressed with their hospitality: all the workers were friendly, accommodating, informative, patient, especially the receptionists. They helped us find tours, taxis and solved any issues. I would repeat FAUNA in a heartbeat!
