Location, location, location - it couldn't be better. Close to Gran Via, as well as the 2 most important plazas, walkable everywhere, and right next to a subway stop. And it is tucked away in a little side street, so it is relatively quiet for a big city. We arrived early in the morning, were met by one of the owners, and the apartment was all ready for us. There is an excellent housebook with instructions, and a map with lots of recommended eateries. It is a brand new space, and everything worked well. We would certainly stay here on our next trip to Madrid.
