Overall, a nice place, and we enjoyed our stay. There are just a few things you should note before staying here, and some areas for improvement.
First, the positives: It is in an amazing location, close to lots of nice restaurants and bars, and full of beautiful trees. In a stylish building, with big and comfortable rooms with nice beds for a good sleep, blackout curtains, hot shower and beautiful balcony. 3 bathrooms and 2 showers were a big plus. The host was friendly and accommodating.
There are some areas for improvement, but I should stress that none of these are "deal breakers", and we made ourselves at home for the 3 days we spent there.
First, the apartment feels fairly dark inside during the day, so I wouldn't want to spend long working days here. Second, the kitchen is not very well equipped, but again for small meals it was enough. It would have been nice to have drinking water available when we arrived. Some nice touches could be added that would make the stay more comfortable.
Fourth, although the apartment was cleaned before we arrived, and it was overall clean, the floors and the shelves could use a deeper clean. Really nothing bad, but it wasn't the cleanest apartment we've stayed at in Mexico City. We also found the balcony to be a bit unsafe - the glass barrier seemed unstable and I wouldn't want to lean against it or have children play on the balcony.
Fifth and finally, the check-in process and entering the apartment each time is inconvenient. Entering the front door of the building requires a cellphone with coverage, which not all travellers would have. Only one number can be programmed, which isn't the best for a group of four people.
These points aside, it is a nice and enjoyable apartment in a fantastic location.
