Lovely and cosy room.
Very close to the subway that connects the airport to the city (linea 8) and that's a big upside.
They gave us a little sweet treat for the breakfast and that was such a cute gesture.
It was also very nice to know that there was a chance to store our luggage the day we checked out until the moment we had to leave Madrid.
The only small problem we encountered was that we had a miniscule issue with the screen used to open the apartment door but they helped us quickly, so no big deal.
A really great experience, totally recommended.
