We stayed at Stephanie's apartment for an entire month! The location is amazing. Easy walking distance to lots of great restaurants, street food, cafes, etc. This spot is truly in the heart of Roma and an easy ~15 minute walk to the heart of Condesa.
Stephanie was very responsive and accommodating. She helped us to get checked-in several hours early. We had an issue with the drain and water pressure in one of the bathrooms, but Stephanie was able to resolve these relatively quickly by having the maid clear the drain.
We were pleasantly surprised to learn that our long stay included one visit by the maid.
I would say that the space is much less bright than one might expect given the photos and the window locations--there is a large tree outside the windows that shields the apartment from a lot of natural light in the bedrooms and in the common room. The room by the entryway, receives a lot more light, but there weren't a whole lot of places to sit there.
Additionally, I think this is quite common in Mexico City, but we did find that the apartment is quite noisy, since it is on the second floor overlooking a very busy street and the windows don't provide a lot of sound isolation. You can also hear a lot of what's going on from other apartments in the building like dogs barking. Stephanie provided ear plugs for our convenience, which we appreciated, but this is a detail that should probably be noted by anyone who sleeps lightly or requires a quiet environment during the day for calls.
