You should stay here! It is extremely well-located and you can walk to everything all over Madrid. There are yummy cafes around the corner for breakfast, too. The apartment has everything you need and enough space to settle in. You can also wash your clothes here so you can pack less! You will have to walk to the 5th floor, but it's good exercise. And if you need a place to stash your luggage after checkout, there is a luggage locker service on the ground floor of the building. Very good hosts, quick response time, and helpful at check-in!
