The apartment is great, new, clean, you have everything you need. The best thing is the terrace over the roof tops of Madrid :) we spent a lot of time there relaxing, sunbathing, having breakfast, it was amazing! The apartment is nicely in the center, when you go down you have a lot of bars and restaurants and a lot of metro stations in walking distance. We had an awesome time! Guillermo is a great host, we could ask him questions anytime and he was always there to help out.
