The apartment is very well located right in the center of centro histórico but for such a noisy part of Mexico City it's really quiet. Also it is very close to the metro (which is useful and cheap). It is thoughtfully designed and lovely furnished. The room had a lot of storage space and the bed was very comfortable.
Bernardo was a great host, letting us in earlier as our flight arrived in the middle of the night. He was very helpful and kind and allowed us to use everything we needed (especially the washing machine).
