We contact Isi before trip and got fast reply. She was very friendly and answer on all our questions. Unfortunately we did not meet her personally.
Location is very good, you can walk from the train station and walk to Duomo without using transport or taxi.
Apartment looks exactly like on the photo, we had room with red wall. Window is going on the road, so first night we were not able to sleep - it was very noisy and loud even with closed window. For second night we bought ears protectors and slept well. If you are sensitive for noise - I would not recommend this room.
