Find another hotel, there are tons of good ones in Oaxaca. This is not it.
The hotel is unlike anything from the pictures that are advertised. The hotel is centrally located and in the historic centre. Yes, if you are unlucky and get a room facing the street it does get loud as there is a bar/restaurant with a roof-top bar right across the street. Light sleepers will not like this. The courtyard of the hotel, the inside, is quite dark and desolate. It's as if others have already avoided this hotel. In advertisements a renovation was mentioned, the rooms are far from recently renovated. The bathrooms look old, there is no chair to sit down in the room, no table to put
