This place is perfect. Check in was easy and Ysabelle was so helpful and nice. She even baked us a cake! The location was great. Only 5 blocks to the train station and 2 to the subway. And very easy to walk to Sol, the Prada, Retiro Park and other must-see Madrid destinations. Everything was clean and coffee/tea and adapters were provided. The building was quiet and there was a lift to the 5th floor. Highly recommend!
