I could not recommend Valentina's place more. I didn't meet Valentina herself, but her father, Claudio, was extremely hospitable and kind. He picked me up from the train station, as I arrived after dark and I had some luggage, and brought me to the apartment. He was very communicative and replied quickly to all of my inquiries. I felt very welcome and also very safe at the apartment, especially as a solo female traveler.
The apartment itself was very clean and comfortable. I'm pregnant, so unfortunately I couldn't drink the complementary prosecco, but I appreciated the water, milk, and breakfast items available! The location is excellent, very central so you can walk anywhere downtown. There are so many great cafes, restaurants, and bars nearby, as well as grocery stores and sights to see. Being centrally located there is city/street noise, so pack earplugs if you're sensitive to that at night, but it wasn't a problem for me.
I have only wonderful things to say about my stay here. 10/10 would recommend!
