We found this apartment very convenient and clean. Central location, close to Duomo and shops, and elevator made it ideal (3 steps up to elevator) for our group. 1 double room with good storage and small ensuite with shower, 1 single room with 1 single bed and 1 fold down single bed (little storage), good sized main bathroom with shower. Living/kitchen/dining area had a sofa bed which we didn’t need but it was comfortable as a sofa. Good sized smart TV (no English channels but we could use streaming services). As others have said, air con not great but fans were provided.
Host let us leave luggage and collect later which we really appreciated.
