Staying at Claudio's place was great. It was my first experience with airbnb. Claudio was a super welcoming and helpful host. The apartment is located in an old building with tall ceilings and climbing the steps to the fourth floor is a little workout, but very much worth it! The place is in the very center and really easy to find coming from the train station. It's clean, the room spacious and the private bathroom a small luxury. Also, there's lots of neat cafés and restaurants close by.
For people with special food needs: there's a vegan restaurant down the street called Dolce; a pizzeria that serves amazing gluten-free pizza called The Club House on the block; and an adorable family-style vegetarian restaurant called Il Vegetariano that I can recommend. Also the vegeterian kosher restaurant Ruth's next to the synagogue is only 10 minutes walk away.
