You can't beat this apartment for location. It's right next to Puerta del Sol, easily accessible by metro or a short walk to most central attractions in Madrid. Pablo was quick to respond to questions whenever we needed him. He was also very accommodating and let us leave luggage behind after check-out while the apartment was being cleaned. The only slight downside was the night club below the apartment. We were there on the weekend and it was active every night. Clubbers were coming in and out, and on Saturday night- loitered on the street below our bedrooms windows until 3am, chatting away. Despite the thick windows in the apartment, the noise disturbed some of the people in our party during the night. If you're a light sleeper, it's worth considering.
