This is a very clean, comfortable, stylish place to stay right near the Opera Metro in the center of town. The building faces onto a plaza that is relatively quiet at night. We were very warmly greeted by Bruno, who took the time to give us a map and point out various places to visit and find restaurants. Having access to a kitchen to make tea in the morning was a bonus. The only issue we had was noise from other guests late at night who didn't respect the quiet hours, as the walls are thin and noise carries in the apartment. Overall I'd say it was a good value for Madrid, and I would recommend to a friend.
