Wonderful apartment and although a walk-up it was well worth it for the beautiful apartment. The nights were quiet in the rooms which was totally unexpected and wonderful. Only concern would be for those staying in the summer both because of lack of AC. Amanda did offer to bring fans so I would suggest requesting them if there is any chance of warm weather during your stay. we had unseasonably warm weather for April. The street in the entrance area is not as clean as other parts of Madrid which is surprisingly clean for a major city as a whole (might have just been the couple of days we were there because it was a holiday). Overall the excellent quality of the apartment accommodations and the ideal location to get to everything in Madrid center well outweighed the negatives.
