Our party of 5 (2 couples and an adult daughter) stayed here for 3 nights in May 2017. It's in the historical centre, exactly as advertised. The 3 storey apartment is full modernised inside and is a comfortable, contemporary conversion of a medieval building, done by Angelo's architect wife. Just off Via Roma, the narrow street and nearby square is a local's bar, street food and night club hangout, and is authenticly non-touristy. But be aware the bar's music belts out into the early hours Thurs-Sat (earplugs are provided!).
Angelo was a great host and was very helpful to us. The apartment was very clean and well-equipped and walking distance to all the city sights. We'd recommend it!
