We stayed for a month. The apartment is well equipped and everything worked. There is a 24h doorman which provides a measure of security. We also appreciated the safe for storing valuables. The drawback is the major road right outside the window. The windows insulate well and we had no problems sleeping but there are occasional loud motorcycles, sirens and bright police lights. Due to pollution opening the windows does not seem an option. Nevertheless, we had a good, unproblematic stay. There are a lot of restaurants in the immediate neighborhood and zona rosa and roma norte are a 15-25 minute walk away.
