Great spot in Condesa which is an incredibly convenient, and beautiful location. Many excellent restaurant choices close to the apartment (Rojo Bistro and Maque are some personal favorites) . Additionally, it’s an easy and economical Uber ride to just about all the sights.
Though the apartment is compact, it has all the amenities you could hope for including filtered water and washing machine and dryer. There's also a heater and air conditioner available as the need arises.
Though I adjusted to the compact nature of the space, there is a step up/down between the sleeping area and living area, and then into the bathroom, so extra attention overnight is something to be aware of. Also, as other reviewers have noted, it's a walk up, so if you have mobility issues it might not be a good option for you.
A great spot which I would recommend as a very central, convenient and attractive location.
