Check-in worked perfect. It is just 5 minutes walk from the apartment. Everything was as shown. Location is very central, most places could be done by foot and two metro stations are within 5 minutes. Since the apartment lies directly on a crossing of Gran Via with another road it is really noisy during the night. But this works with closed windows. Only thing to be improved is that the clock of the aircondition is reset to midnight everytime you start it (by entrance key). I could not find out, how to let it work constantly during the night. And since the bathroom has no window, mould is starting to build up. But otherwise the apartment was very clean and well equipped.
