We had a lovely stay in Rosanna's studio. Rosanna was always very quick to respond to our emails. The apartment is very clean, modern and close to the train station and city center (15 minute-walk). It is however located a bit outside the old town, but still reasonably close so you can get there in a 30-minute walk. We also really appreciated that Rosanna had her son pick us up from the airport, but in any case it is very easy to reach the apartment by train from the airport.
