Cesar's place was great--it is a private room and an en-suite bathroom within his home. The room was the perfect size for me, complete with a closet and bathroom amenities. The apartment was located on a quiet street, just off Calle Atocha and is extremely close to the big museums in Madrid as advertised! Both Cesar and his family were very kind and were there if I needed anything. Cesar was especially helpful in providing me with a city map with some highlights circled as well. Would definitely stay here again!
