The place was a good deal for the money, including the rather annoying feature, which is a noisy street right below the windows, where the cars are heard during the day and night. It was very hard to sleep with open windows and due to no A/C and late afternoon/evening sun straight into the windows, the flat was pretty hot inside (the blinders are there but the sun is just too strong during the summer).
Other than that, the place is as described, the location is very good (2min walk to a subway station, walking distance from presidential palace and beautiful parks). The neighborhoods seems pretty safe, the building itself is in a good shape with a pool and laundry room.
Cristian was extremely responsive before and during the stay, reacting immediately to any question, was kind enough to wait for us to let us in and then showed us some places to eat. The water was warm, the wi-fi and TV worked very good.
