It was our first experience with airbnb and it was very successful! though oscar was out of the country he arranged for his friend ricardo to wait for us until we arrived to madrid. due to the flight delay Ricardo waited for us almost until 11 pm, was very helpful and welcoming. The apartment is perfectly located - 10-20 minutes walk to anything you may want to see in Madrid center. At the same time it is very quiet, though close to a lot of tapas bars and restaurants. nice supermarket is just few minutes by foot. The apartment is in an old building, small, well equipped - have everything necessary you may need including Wi Fi. would definitely recommend to consider it as a place to stay in madrid!
