Overall we had a "good" stay at Juan's.
Start with the good... Good location and very walkable to Roma Norte, La Condesa and (while we didn't get there) Polanco. Also, very good was Juan's communications, directions and responses. Very prompt, clear communications made getting in and out very easy. Appreciate the door man always on duty. Filtered water in the apt was a plus. TV worked fine.
Next, the "just okay"... the location is parallel to a very busy road with a good bit of road noise. We went in late November and while our windows were closed there was still a bit of an issue at night sleeping due to the traffic noise. The apartment is smaller than the images suggest. We had 7 and felt cramped. Cleaning was good, but overall the place was tired.
