Pros: Nice and relatively new apartment with good communication to the city center. Rooms are spacious and everything was clean. The balcony is the best part of the flat with great views from above the building. Attentive host offering to help before and during our stay.
Cons: the kitchen equipment is quite limited and would benefit from additional silverware, pans, and a microwave. Noisy at times due to an elevator box next to the apartment. The bed is small.
Overview: overall this is a good alternative to visit Madrid. Visiting during some of the sunny months will allow to enjoy its terrace.
