My mother and I stayed here for four nights and had a lovely time.
The rooms are lovely and spacious, and beautifully decorated; exactly like the photos.
The beds are firm but not hard, like you find in a lot of hotels. Fully equipped with thick duvets for the cold winter nights. We didn't need them though as we traveled in May and the evenings were not cold. The shower is amazing and the kitchen is equipped with the basics.
I felt completely safe here at all times, even with the windows open at night. The apartments are just a few minutes walk away from the main square which is great to sit in and relax, or go to the cafés and have a coffee and a churro. Don't miss the Sunday markets and do try the street food. Coyoacán is famous for it!!
