Rut was a wonderful host. Check-in and check-out were very easy. Rut let us leave our bags at her own personal apartment (in the same building) before check-in time since our train came in early, and after check-out time since our train didn't leave til nighttime. She could have easily told us to leave our things elsewhere, but she decided to make it as easy for us as possible. Thank you, Rut!! She and Oscar were responsive to emails and very accomodating with our odd timing schedule. The apartment was very clean and very stylish. Don't let the fold out beds in one room scare you - they are very comfortable. The apt is small but we did not find it uncomfortable for 4 people. It looks exactly like the pictures. It's in walking distance to all the museums (Prado, Reina Sofia, Thyssen-Bornemisza, etc) and to many bars and restaurants (Plaza Mayor, Plaza del Sol, Plaza de Santa Ana). Great apartment, great hosts, great location!
