Condesa/Roma Norte is a beautiful neighborhood and this is a really nice apartment building. The neighborhood has tons of nice restaurants and bars, really close to the park and pretty good if you're looking for transit (though Uber is super cheap, so it dominates most other options).
The gym in the apartment is more than adequate: a pair of treadmills, a few ellipticals and some weights. The building staff is really friendly and helpful and it's nice they don't seem bothered you're there with an AirBnB.
The apartment itself is big and pretty nicely furnished. Mauricio is really responsive and helpful.
So on the essentials, all good things. A few basic upkeep issues (no shower soap/shampoo/cofffee) is the main reason I wouldn't give it 5-stars, but I'm sure that can be fixed in the future.
