GREAT APARTMENT!
Excellent location, just a block away from Sol and the subway! The apartment was very clean and the beds super comfortable. Madrid was my last stop of a long trip in Europe, this apartment was the best place we stayed in, even better than some hotels. I was traveling with 5 more friends and we were all very comfortable, it never felt crowded. It has Air conditioning, which was great, and a very well equipped kitchen.
The hosts left maps and guides to the city for us, as well as some breads, tea and coffee for breakfast.
