I stayed here for 5 nights as a homebase for exploring Mexico City. It's SO cool to be on the rooftop of a building with a gorgeous and tasty restaurant at the bottom! The view of the park was really pretty from the deck that's right there.
Other things I loved:
Walking distance to most of the museums and lots of restaurants
Really cool kitchen with plenty of filtered water and a snazzy coffee maker
WiFi was always excellent
Hot shower
They do your laundry for you!
Here's what I didn't love:
It's four flights up teeny tiny steep stairs. Good for a workout!
The noise from the park below: always dogs barking, and quite often, street vendors with megaphones!
The deck area was quite often occupied so I rarely was able to use it
Wasn't given a key to the safe, which would have been nice
A few extra tips:
It gets COLD at night in January - ask for a blanket for your bed so you don't freeze at night!
Get the "Pappardelle with Ragu" for dinner from Cafe Toscana. EXCELLENT!
