Check in was very easy. Sandra was very responsive with any questions I had prior to check in. The guards in the building were very nice and helpful. Our flight was very early and the guards were kind enough to look over our luggage before it was time to check-in (we made sure to tip them). The space was clean and just as pictured/described. There was plenty of hot water and water pressure for two consecutive showers. Although there isnt any AC in the apartment, opening the doors and having the small fan running kept the apartment cool. The Oxxo a block away was super convenient. The apartment is on a major street so if you are a light sleeper you should bring ear plugs. We slept fine since we were out all day and tired once we got back to the apartment. I would recommend Sandra's apartment for your stay in Mexico City.
