Communication with the host was very easy and he was very responsive to my questions and needs. The apartment is located among a large number of great bars and cafes and it was perfectly located to walk to many museums (Prado, Reina Sophia) and great access to all public transportation (buses, metro, and train station). My friend and I had a wonderful stay and remarked at how many more tapas bars we would have loved to try that were just within a couple blocks. We will just have to return someday.
