I stayed for five nights at the apartment of Serena during a film festival with two other friends. Serena was very friendly and the communication was really easy and helpful. We very much felt at home at her place which is really really gorgeous! A true home abroad!
The aparatment is very centrally located and the bars on the streets and the mercato del herbe are some of my favorite places in town.
The apartment itself is really spacious and is perfect for two couples or a family. The second bed might be a bit too narrow for two people that are "just friends".
