It's the perfect stay if you have flight in the morning, but not for more than one day. The house is more a cave and is made by putting a roof between two pre-existing building (is it safe?). There are two doors, one facing the street and the other a small garden in common with another apartment. It's difficult to be vented and therefore if you don't enjoy turning on the fans during the night it becomes very warm. It remains quite far from Madrid city center, we paid almost 50€ to go back and forward with bolt. It is nevertheless 3 min on foot from the stop of the 101 bus that takes you to the airport in 8 min (T1).
