I must absolutely recommend that flat! Is is located in a safe an nice district which you can easily explore walking (and there are lots of cafés and restaurants).
The rooms a very clean, modern, and equipped with everything one would need (and even more, like a tap with drinkable, filteres water).
The staff is very nice and helpful and made our stay very uncomplicated, even as we had to arrive quite early for the check in.
I'll definately stay in that flat again once I'm back in CDMX.
Thanks, Francisco for all the service!
