Martin was a very communicative host- he answered all of my questions in a timely and accurate fashion. The apartment was as listed and in a great neighborhood- very close to the subte, bars, cafes and restaurants. He did get a little bit prickly when we wanted to check out a few hours after the agreed upon time but eventually relented and said it was ok. The apartment was generally clean and I would stay in his apartment again the next time that I'm in BA.
