Great apartment (pics are very accurate) in a good low-key location. If you don't want to stay in the hubbub of La Roma or Condesa, this is perfect -- walking distance to those areas, and lots of small local restos and street food around.
Our only issue was checkin -- the host was an hour and a half late and communcation was not too smooth during the delay. She said it was because she got into a car accident, in whci case most of the delay isn't her fault -- but she was already running late before the accident, and communication could ahve been better.
She suggested that we shold wait at the cafe on the corner -- but then she didn't come through on her promise to cover the bill. It wasn't much money, but would have been a nice gesture as we waited on the street with luggage for over an hour before going to the cafe.
