Amazing place to be able to stay! I just would ask for the bedroom on the backside. I think the street in front is a bit noisy and the blinds/windows don't close completely. Further on: kitchen, bathroom are excellent. Internet was not working.
Only some 100m from the railroad station and 500m from a huge (german) supermarket (via roma). All central parts/sights easily reachable on foot; well situated!
A unique chance to stay in a 1920's, super huge apartment!
