This location was absolutely perfect. It is only a few minutes' walk from anything that you need, with a few Metro stops within a 10 minute walk. Close enough to the sites, but just enough away from them to not feel the crush of the waves of tourists.
The apartment is well furnished and very comfortable. We had an extended stay and cooked several meals and the kitchen had everything that we needed. The main bedroom suite is separated enough from the living area to allow for space but also close enough to be able to be together. Beds are comfortable and the air conditioning in each room helped tremendously. There's a washer & dryer in the main bathroom.
Our host was instantly available and was very helpful in orienting us to the apartment & city.
This apartment will be our first choice when we return to Madrid. We recommend it without reservation.
