The room is very comfortable and you get everything you need. We stayed for a week and really felt like at home. The area is really convinient, you can walk 10-15 min to the main attractions in Madrid. We had a big suitcase and it was not a problem at all to walk to the train central station Atocha. We highly recommend to visit the market around the corner "Mercado Anton Martin", it offers a lot of lunch possibilities.
Unfortunately for us, Ben was in a job related trip, which means that we had the flat for us and his cat (Sony). However, we had contact with Ben all the time, he was very interested that we felt happy at his place. At the end of our visit we got to meet Ben personally, it was a nice experience, because his energy and warm welcoming attitude made us felt as if we have been friends for years. We can only say that Ben is an amazing host.
