Luis's apartment was beautiful located only steps from the Gran Via. Our flight arrived early to Madrid, and although we were not able to check in early, Luis did direct us to a "Lock and Be Free" where we could leave our luggage while we explored the city. The apartment was clean, all of the expected amenities were included. We were met by an associated of his who let us into the apartment at check-in. We felt very safe/secure with multiple doors to lock as you go in and out. I would caution that because the apartment is in the center of a bustling street, it can be very loud on the outside street all the time. The shower does have cycles of hot and cold water which was not that big of a deal, and seemed to be an issue for us in other places too. I would certainly recommend this apartment to others, especially younger travelers.
