I stayed a month. Aidé and Carlos are easy roommates, always willing to either answer questions or give you privacy. You can tell they've hosted a lot of people; they're very relaxed. The room's simple and nice; mattress is comfortable (medium firm); nice little bathroom, on-demand hot water. Carlos is immediately responsive to all requests when you're there, and quick communication before you arrive. There's one dog now (Taz), who does beg a bit but goes away if you ignore him, but he's nice friendly dog. Obviously, you need to be cool with a dog to stay here (I am, so Taz was sort of a plus). Biggest bonus for me was getting all the local tips from Carlos and Aidé, all the small myriad details that only locals know. Also, building's very safe, 24 hr. guard on the door.
