The apartment at Puerta del Sol I was the perfect place to stay in Madrid! It's right in the heart of Madrid, but still very quiet with the windows closed. It's on the top (5th) floor (with elevator) with a nice, small balcony to sit out on and relax and see the stars at night. And the air conditioning was so perfect and essential on the super hot summer days I was there. I highly recommend this apartment and would love to return sometime again.
