Great location near Zattere ferry station, you can take the ferry from the train station to the building if you want. The unit is on the 3rd floor, and the front door lock is a bit tricky, but keep at it - it will work. The unit is large - you can sleep 6 if you need to, and has what you need, including air con.
It is quite simply decorated, like a dorm or hostel. Which is fine, because it is really good value, but you shouldn't expect luxury.
We really enjoyed our stay.
