I've stayed in places like this, but not at this one. They are usually spartan but clean. There are two things you need to ask; do they have internet, and do they have a curfew. The curfew is a particular problem because it is usually 10PM. That's when they go to bed. You don't get a key. 10PM is a problem, since restaurants don't open until around 7:30-8:00 PM. Miss curfew, and you will be out in the street looking for a hotel. I don't know about this place in particular, because nuns gallery is like a hotel chain, with multiple branches in many countries, including the USA. I think they have six "guest houses" spread around Italy. The rate sounds good, but make sure you ask the right questions, especially about the curfew.
