I had a good stay in this apartment. Luis is a good host, always available to answer your queries.
The building has security 24/7 and the key of the door is a card.
The room can be a bit hot in the morning, on a sunny day, since the sun hits the wide window of the bedroom, and there's no airconditioning or fan.
The building has a washing machine and a dryer that you can use whenever is free.
If you stay for a month, they offer you free cleaning every week.
The only thing I missed was a cloth hanger to be able to dry my clothes that are too fragile and sensitive to be put in a dryer.
The location is amazing, on a quiet street right next to chapultepec park, and many great restaurants in condesa.
