Great location and sufficient space to allow family of 6 to use as a base to explore Madrid. 3 full bathrooms allows for faster times getting ready. Due to a missed connection, we arrived very late at night and we were met at the apartment for check-in (for an extra fee that was disclosed in advance).
Due to the location of the apartment, there was significant noise at night - as mentioned in other reviews. I wouldn’t recommend for a family with small children who go to bed early.
