Cris' place was an excellent base for our week's visit to Mexico City.

It is very close to a metro station and two metrobus stops, including one on the main North South bus line so it is very easy to get to any part of the city (including the airport Terminal 1), and the tickets are very inexpensive.
There are many places to eat, from street food stalls and cheap takeaways up to some of the best restaurants in the city within walking distance
It is also only a few blocks walk to a major supermarket (Superama - part of Walmart) to buy supplies to eat in.
The area felt safe to walk around and whilst we were vigilant given the reputation of the city, at no time did we feel any concern or threat - on the contrary we found the people we came in contact with to be friendly, kind and helpful.
The apartment itself is stylish, comfortable, well equipped and very clean
There is 24 hour security at the entrance so it felt very safe
There is a lovely balcony to sit out on and flowering trees outside
There were also thoughtful touches on arrival like bottles of water in and out of the fridge, and little chocolates on the beds.
It is situated on a quiet cul-de-sac, so although there is some noise from the main road nearby we did not find it disturbing even though we are light sleepers
Check in and out was easy and straightforward
We were very pleased to get a chance to meet Cris and his Mum as they came to take away the TV for repair after a power surge had damaged it - they were both really lovely people, and concerned to make sure guests had the best possible experience.
We would definitely stay here again if we returned to Mexico City
