It's a nice flat, neat the city center, perfect connection by the underground or buses, stations 3 minutes of walk, 10-15 mins. to center, 45-55 to the airport. The terase was awesome, a great view, unfortunately we could not use it because it was raining. In general I would recommend to use this flat in summer, since we visited Madrid in November, it was raining, windy, cold at night and the rooms were a bit cold as well (not a bad of the flat, nothing is perfect). Quini was a great host, even though there is actually no reception, it was not a problem to check-in after midnight (her son was waiting in the flat) and check-out later at afternoon. Plus fast answers in chat. Thank you again, we really enjoyed it!
