Check in was really flexible, and the lady was really kind. The apartment has everything you will need on your trip to Madrid. We stayed for work at the IFEMA, and it was easy to get to with a cab.
If you have a big van, like we had, you should consider parking it outside the city centre. parking was terrible.
Balcony has an nice view over the city centre and has enough shadow I the afternoon to sit in.
really nice apartment!
