Very good experience, overall. There was a small misunderstanding, due to my fault, but everything worked out well in the end. The place is clean and quiet.
Make sure you bring enough soap, shampoo and toothpaste for your stay - but if you run out, you can buy it from the host's store that's located on the premises.
Overall, I had a pleasant experience during my stay with this host in Mexico City. Communication was very efficient, and they respected my privacy.
Only recommendation to the host: please fix the main entrance door. It has been broken since my last stay about 3 months ago. It is very uncomfortable and unsafe having to stick a hand through the little window in order to open / lock it, especially at night.
