I spent two nights at Marianna's place. The place was very clean and nicely curated. She was prompt to help us with anything we needed.
The apartment is located in a very typical and "popular" area of the town. If you do not get intimidated by the narrow and old streets, you will enjoy a lot. The location is great, walking distance from the main train station and to the city center. The plus is that one of the most important pizzerias is one minute away.
