Rosalia's place is located in a beautiful building and is both very central and very quiet, as it looks onto a beautiful inner courtyard, away from traffic (although sound insulation could be improved).
The apartment itself was fine, although it wasn't very clean. The sofa had some big, visible stains: when we complained the host sent a cleaner to take care of the more visible problems. The sheets were smelly and not perfectly clean, and we were later given further sheets upon we complained.
We appreciate the fact that the host took care of things (we were also brought a kettle and a coffee machine which were missing initially, despite being included in the ad).
On the whole we had a good stay, as the place is beautiful and the location awesome.
