We enjoyed our stay at Germana's place. The house is like in the pictures, in a quite and friendly area. Very close to public transportation (tram) and only 6 stations to the Duomo (you arrive there in 10 minutes). We were a bit concerned about the heat in the house because we traveled in January, but everything was ok. The house is well heated.
Also, Germana reccomendations of places to visit and restaurants are very good. You should try them!
