The apartment is spacious with a nice lounge / diner area; two bathrooms was particularly good for us, as was the reserved secure parking space under the building. It is well located 3 minutes from the metro station and has a good selection of restaurants within 5 minutes’ walk . There are also some local sites to see and we walked into the centre of Madrid a couple of times.
The key pick-up was very flexible, which was handy given our flight delay, and the owner was extraordinarily helpful, even with matters not concerning the apartment.
Highly recommended.
