This is one of a dozen AirBnB apartments in a renovated building managed by a group called Casai. The apartments are laid out differently, but outfitted identically, and the pictures and descriptions are accurate. So it's worth looking at the different apartments shown on the Casai website and on AirBnB, and choosing the one that looks most attractive to you. This particular apartment is among the nicest - top floor (4 flights of stairs), patio door that opens onto a balcony with sunny southern exposure, and a 2-in-1 clothes washer/dryer in the apartment.
The agents - in this case Rosalia Dawn - are very conscientious and attentive. Rosalia answered all my email questions within minutes. The location is very quiet, surrounded by restaurants and cafes, and no more than a 10 minute walk from the Juanacatlan and Patriotismo metro stops. The building has 24 hour security guards, who let you in. The apartment locks are keypads, so you don't have to fiddle with keys; they send you the keypad code at time of check-in. Safe, clean, convenient, modern, comfortable, reasonably priced. Hence: recommended.
