I enjoyed my stay at this apartment. It was a beautiful studio, full of bright hardwood floors and white surfaces. The washer was convenient to have. They left me two Coronitas, a big bottle of water, some laundry detergent, and a little coffee. The balcony was wonderful, and you could see most of the sunset over to the west, and there was a great view of the Chapultepec Castle. There were three doors out onto the balcony (one didn't work though—and the one in the bedroom seemed to be splitting another balcony for another apartment). It was an easy walk to the park and into Condesa, and a short walk to the Metro which had easy access to Coyoacán and downtown. It's great to have the 24-hour doorman to let you in, and there's a post box right down the street if you have any postcards to send.
The apartment does come off as someplace more hotel-like, and not someplace anyone actually lives—not always super functional. The door separating the bedroom from the rest of the apartment gets stuck four inches from being actually closed. It's also really difficult to move—you need to lift it, and as I closed it, my fingers got stuck in it multiple times. There was no plunger—I had to get one from the doorman. There is a washer but no dryer, which is totally understandable, but there's also no drying rack, so you have to hang things throughout the apartment, which is worrying because they asked to be very careful about liquids and the hardwood floor. The headboard isn't connected to the actual bed, which just required some readjustment every night before bed.
The responsiveness was almost there but not quite. They got back to me very quickly but often would forget one of my questions, or sometimes they just sent me generic messages advertising certain things in the neighborhood instead of answering. They helpfully came once to fix the plunger issue, and when I got home the balcony door was propped open and it was hot in the apartment as a result; and the balcony door never locked after that, and they never responded to my questions about why the key was no longer working in the lock.
