We had a great stay! The apartment was bigger than it seemed in the pictures and easily accommodated our family of 5. Despite the location, it was relatively quiet. There was some noise from other guests in the building returning at night, but nothing extreme or disruptive. The location is fantastic, right by the metro/renfe station with easy access to subway or cercanias train (helpful during a taxi strike!) and in the heart of Madrid within an easy walk to many major sites as well as restaurants. We would be happy to stay here again.
