Alfonso gave us the best welcome we have ever had using AirBnB. He has a lot of knowledge about the neighborhood and Madrid in general and gave us a lot of good tips on sights, food and life in Madrid. The apartment is located in a vibrant neighborhood, so it can get a bit noisy at nights. However, the location is super cool and charming, and all sights are at walking distance (around 20 minutes to the Prado museum, and the same to the Royal Palace).
A stay at this apartment is highly recommended when in Madrid!
