I spent two days with my family at Barbara's palazzetto the very first days of 2015. During the reservation, I had some problems with my credit card and Barbara was super-kind and helped me to get through. Natasha was also kind, she was on time for the check-in.
Check-out was also flexible. The house is cozy and the position strategic, away from the crowd but walking distance from the main attractions (15 min).
Bathrooms were tiny for our needs, but everything was clean and in perfect conditions. The steep stairs are not ideal if you are an elderly person.
