The flat is very nice and clean. The location is good because it's only a short walk to the center of Tlalpan and several stores and pharmacies nearby, but it is on a rather busy street. Traffic noise is less at night, but we still found it a bit hard to get used to. However, it seems like it's not an issue for other people. David wasn't around, but he was still available by phone and always making sure that everything was ok during our stay.
