Carolina's place was perfect for me. Both the room and the adjoining private bathroom were spotless and well-equipped, the bed was comfortable, and it was warm. There is a métro station literally right in front of the door to the building. I didn't see Carolina at all, and only spoke briefly with her husband when I arrived, but they provided everything a visit could need (an extra blanket, plenty of towels, shower gel and shampoo, a drawerful of guides and tourist brochures, etc.) I will definitely stay there again.
