Found the neighborhood first (Condesa is great) then this place. It is well priced and located. Appliances are clean and everything works great. The host met us on time and gave us the keys, left us with water and gave good food recommendations. The area is safe most hours of the day and night, though it is not as fancy as Hipodromo or parts of Roma nearby. Location is walking distance to all the great restaurants on Tamaulipas and Nuevo Leon etc. as well as the subway and museums. The wireless was my only real complaint. It is a building wide connection that is un-reliable. We also had a small issue with noise as this is a street-level unit.
The grocery store, torta place and cheese store on the same block is a great convenience.
