Gianni was a very correct host. The location is very central and surprisingly quiet! The view to the back of the duomo is great. The room was as described in the photos, very original and clean. The ambiance seemed to us very welcoming and similar to a hostel. Breakfast was available for free in the kitchen.
We were really satisfied with our stay at San Genaro, although it was sometimes hard to get the flush in one of the bathrooms to work.
