We stayed a week in the small apartment of Andres and Francisco and were overall happy with it. The check-in was smooth, the rooms were well cleaned and welcoming. The entrance and main window face a backyard, accordingly there is little noise from the street to be heard. We had the (mis)fortune to catch some very hot days in the city during which also the apartment became quite warm, but overall bearable. In the bedroom, a small ventilator is provided that could ease the heat a bit during the night. Kitchen and living room are rather small and equipped with basic dinnerware, which might lack some things if you want to cook. However, there are a lot of nice restaurants in walking distance.
The area is great, many things to see and eat and room for nice walks. Public transport, in form of the metrobus, is running close by (Av. Insurgentes, 10 mins walk), which we found quite convenient.
Over all a nice stay with kind and caring hosts, thanks!
