We stayed in Olivier’s flat for 5 nights. It was fantastic! The location is in the heart of it all with a direct balcony and view onto Plaza Mayor! The subway station is less than a 5 minute walk. Olivier’s communication was immediate and he was so incredibly accommodating. He even had all of the essentials needed, as well as extras like bread, jams, yogurt, coffee and tea for a great breakfast start! He even provided maps and tourist books of all we needed for a quick tourist visit. We felt completely at home. I would highly recommend staying here if you are coming to visit Madrid!! 5 stars! Thank you, Olivier!
