I booked the apartment for my parents, and they were very satisfied. Valeria's place is a real gem, with an authentic atmosphere; Valeria is very friendly and warm, and really cares for her guests.
Very clean, and with everything you might need for a short stay. If it happened that my parents needed something extra, Valeria did her utmost to help them. The only downside is that the bath tub is very high, which could be a bit dangerous, especially for older people.
All and all, Valeria's place is highly recommended.
