We stayed with Jacopo in April für a little over a week and had a great time.
The flat is fairly close to the city center and we walked almost every day. There is however a tube station close by.
The room is small but more than enough space for a holiday stay.
The information Jacopo provides concerning restaurants, sights and off-the-track areas are very useful and we ended up doing most of the things he recommended.
All in all we had a great time and would definitely stay there again.
