Highly recommended. We used booking.com and got a double room for 89 euros / night. When we arrived, they didn't have what we had wanted, so we were given a triple instead, for the same price. It was a very large, clean room, overlooking Gran Via, but quiet. The beds are super-comfortable, with controls to adjust the height. The minibar has free drinks (no alcohol). It also has safe, iron and hairdryer. There was a rooftop jacuzzi included in the price, open until mid-September. Yes, it's small, and the water was cold, but the views over Madrid are priceless! In addition, the hotel has a hairdresser and spa.
