Lorenzo is a great host, friendly, always ready to answer any question that you may have, quick/clear communication before arriving.
The apartment is just like in the pictures good and clean, kitchen is well equipped, enough space and you really can see the Duomo from the window :)
It's 10/15 min walking from S.M.N. trainstation and in the middle of the city centre so during the weekend you can have a little more noise from the streets.
