The apartment is really beautiful and spacious, and Benito was a very thoughtful host, leaving out croissants and snacks, as well as cute little toiletries. It's a modern apartment with a great kitchen and bathroom, and the room comfortable for a single person. Wifi worked great. The location is central, just a couple of minutes walk to the Anton Martin Stop (Line#1) and walkable to the main sites in central Madrid. I didn't meet Benito but he was prompt at responding to messages, so everything went totally smoothly.
