Nice, clean and comfortable flat in one of the best areas to visit in Mexico City. Beautiful parks and good restaurants nearby. Good kitchen with coffee, tea, etc. I felt really welcome with wine, fruits and bread waiting for me on the table.
Bring some warm clothes, it's a bit chilly in the flat. As somebody else also wrote, the construction somehow amplifies every step the upstairs neighbours take, and the sound is quite disturbing even for a not-so-sensitive sleeper.
Didn't get to meet Eric, but he was very helpful and responded quickly and friendly to whatever question I had. I warmly recommend the flat and the host! Thanks!
