During our two week trip through spain we stayed at four different airbnb hosts, one of them Laura, where we stayed for three nights. Of all the airbnb hosts, Laura was the only one we met personally and we had a very warm and friendly welcome. Obviously she had lived at the place with her family for some time in the past, so it was well equipped and very suitable for the four of us. Beds were very good, and so was the heating, which was especially important, because it snowed during our stay in Madrid in March.
The apartment is in a quiet residential area, with nearby supermarket, shops and public transport (Metro and bus will take your in 20 Minutes to the heart of madrid).
