We had a great stay here for 5 nights. The building is in an excellent location, we were within 15-30 min walking from pretty much everything we wanted to see in Mexico City, there is also a great organic market very close by, as well as a regular supermarket.
The room is large and has floor to ceiling glass doors which open onto a (very) small terrace, great for natural light. We slept with the doors open as there was no A/C and the room got quite stuffy, we found the mosquitos were a bit of an issue but not terrible. One thing to mention is on Friday and Saturday the street is quite loud until the early hours of the morning.
The kitchen and bathrooms were cleaned everyday except one day during our stay but because they’re shared there’s a bit of the grungy hostel feel no matter what. They more than served our purpose though and there was ample hot water for showers!
Overall we found Casa Rm 26 very comfortable and really enjoyed our stay! We’d definitely stay again.
