We loved staying here. The location is perfect, 2 minutes from Puerta del Sol. The apartment is spotless, comfortable, modern, bright, and stylish. The wifi is fast, the shower is roomy with lots of hot water, and it was nice having an elevator. It's on a lively pedestrian promenade, but totally quiet inside. We were there during a cold week, but heaters in the living room and bedroom kept us warm. Sara and her daughter were caring hosts and responded immediately the few times we contacted them. Check-in was easy. We would stay here again in a heartbeat!
