I was there for two weeks and my stay was, hands down, one of my best airbnb experiences ever. The apartment is beautiful, very clean, check-in was seamless, the building itself is lovely, the location is amazing, air conditioning was great (essential in the middle of a Madrid heatwave) kitchen is well equipped, and the bed was very comfortable. I hope to be able to book this place again on my next trip to Madrid. Highly recommend!
