What a great experience! This building is in the best part of Madrid - right Across the street from the famous Gaudi "Betllo House" and on Madrid's equivalent of 5th Avenue in New York - high class shopping and dining. The Mandarin Oriental chose the corner across the street, so you know it';s a great neighborhood! Txell was so quick to respond to all of our questions, and check-in was easy and seamless. The place was airy and clean and the breezes mad the A/C almost unnecessary. The views from the deck are incredible - we highly recommend this place!
