José Antonio's spot is a real gem. The location is hard to beat: peaceful, yet close to public transportation and great bars/restaurants. The room is large and comfortable with nice windows (and blinds to keep out the light in the morning). The house itself is full of beautiful art and has a wonderful energy-- so much so that we ended up spending bunch of time there, mostly during the evenings. We loved hanging out on the roof, which is spacious and full of succulents. Also, fast WiFi.
José Antonio could not have been a better host. He has great recommendations, is an all around wonderful person and an incredible artist/maker. We miss Casa Mérida already and hope to stay there again next time we're in Mexico!
