Lorenzo was very responsive and helpful. The old apartment is huge! We were 6 adults and would have preferred another 140cm bed instead of the 120cm, but for a short stay this was ok aswell. Coming from Finland we are used to have a mattress pad on top of the mattress so I had dome difficulties sleeping, finding the bed too hard. But as a summary: we loved the place! Walking distance to all big sightseeing places and that's a big plus.
I would for sure recommend this apartment.
