Cecilia made us feel most welcome. She had already been really prompt with replies when the apartment was booked and when we arrived was really friendly and showed us round the building and apartment. She also gave general directions as to where things were in the area. During our stay Cecilia was extremely helpful and arranged a really nice taxi driver to take us to Teotihuacan for a reasonable price which was great. The apartment itself is lovely and a pleasure to stay in. The building is very safe with its own security guards and a security code to the apartment itself. We ventured up to the rooftop which is also a great space and gives some perspective on Mexico City. The neighbourhood around the apartment is worth exploring as well as being easy to get to the Metro or Metrobus. Again the area felt safe and we found some lovely parks nearby spotting a humming bird. We weren't brave enough to try the Ecobikes at nearby stations but if staying again would use them around the area of the apartment and a bit further where the roads are much quieter. If you are a bit of a foodie then you will be very well served in this area for street food and restaurants. We are vegetarians and found lots of options as well as more unusual places if you want to explore. We really enjoyed our stay in Cecilia's apartment. The only drawback was on one night a neighbour decided to stay up all night and the accoustics of the building meant that we were also awake for the night. This was an isolated incident and nothing Cecilia could do anything about. I would still highly recommend Cecilia and her apartment for your stay in Mexico City. It is well worth it!
