We just stayed in Alberta's place for 3 days 2 nights - although we have never met Alberto, I have to say it was absolutely one of the best Airbnb place we've ever stayed at. Super high tech, heated floors, clean condo, heated bedroom floors, super high tech lighting, TV has NETFLIX, and very close to everything (shops, restaurants, night life). He was also very informative and very helpful whenever we needed any help. Thank you so much for having us! We will definitely rent your place when we come back to visit Madrid! Muchos gracias!!!
