David & Sergio's place was our favorite that we stayed at in Spain. They were very responsive, even considering time zone differences. They were flexible about check-in and storing our luggage after check-out. They provided local recommendations and helpful information about the Airbnb and Madrid. The place was sooo quiet! Even for being on the ground floor, it was the quietest Airbnb we stayed in. It was clean and cute. There was an AC in each room. The bathrooms and showers were fantastic. It all felt very modern and comfortable. The wifi worked well. The beds were not very comfortable - a bit too firm for me, but I slept fine. I also could not find any extra blankets. But those are very minor things. This is a nice spot in Madrid, in a quiet spot with still plenty to do. There's much to do within walking-distance, and a close walk to metro stops. I would highly recommend this Airbnb and would happily stay here and in Madrid again!
