We had a nice stay in the apartment. The communication with Karla was good, and her mother in law came to give us the key. The apartment had what we needed. Thank you for letting us borrow your place.
Note: Mexico City is cold in doors during the winter time and the apartment had just one small electric heater, so was a bit difficult to stay warm. The bed was bit small for two people so one of us slept on the couch (which could be converted to a bed).
