I came 3 days to visit Madrid with my 3 kids. The apartment is very central and well located. It's as described, with enough place for the 4 of us. As we arrived at the airport at 9.30pm, we chose the option of the taxi sent by the apartment owner to take us. I would not advise you do so, as the taxi was late, he is driving very fast and badly, he doesn't help you with the luggages in the stairs. The day after I met with Oscar who is very nice. The communication with the rest of the team was not so efficient. Other small things: the shutters don't work very well and the heaters were not open before we arrived, so it was cold - it's electric heaters, not strong enough in the bedrooms.Please note that one of the bedroom is relevant only for kids, as the beds are quite small. During the night, you can be woke up by the noise of the street in one of the bedroom or from the people in the stairs in another one. Otherwise the apartment is fine.
