I like this place. It's in a fantastic location in the La Condesa area, and I like the sharing concept a lot, but I would not return for several reasons:
1) The bathroom is downstairs, and my room (Sigma) was upstairs
2) I do not like being around cigarette smoke. It is allowed outside/downstairs in the courtyard/shared area, and the smoke wafts up. Because of this , I couldn't enjoy having the window open.
3) The stairs are very narrow and I had to be super careful.
4) The bed was quite comfortable! The desk and chair were not.
5) Another electrical outlet would be great, instead of the extensions.
