Wonderful location next to Puerta del Sol. Well designed space and great air conditioning during the very hot days of August. It was remarkably quiet due to the double pane windows. Once inside one would never know that you are so close to the epicenter of activity in this neighborhood. An added bonus is the great Corte Ingles grocery store a few steps from the building’s front door. We have stayed in several places in this vicinity in the past and this apartment is far and away the best. We would try to book it again next time we are in Madrid.
