We had a wonderful month-long stay in Casa Quetzal. The location is absolutely fantastic, and you can walk out the door to many restaurants, bars, cafes, and cute boutiques. It is a very safe area in Mexico City, and you are right near Tierra Garat and Boicot Cafe for your coffee and co-working needs, as well as Rosetta Bakery, which is a must in town (try the guava rolls, you won't regret it).
The apartment itself is modern and beautifully furnished. The water gets nice and hot, and there is wonderful water pressure. The bed is SO comfortable, and the blackout shades are a lovely touch.
There is fast internet if you need to work from home, and the hosts are very fast to respond to any of your needs.
One thing to note: the espresso machine in the pictures was not there when we moved in as it seems it was broken by a previous guest. There is a sizable french press though, so we were still able to make fresh coffee in the mornings. :)
Having a door code is fabulous because you never have to worry about taking keys with you, and there is weekly cleaning service which was a wonderful surprise.
We absolutely loved our stay in Casa Quetzal and recommend this unit to anyone staying in CDMX! :)
