Friends of mine (two adults + two kids) spent a week in the flat. it was spacious and very clean like the photos. the check in was flexible (we had one hour delay), friendly and fast. In the surrounding area there are a super market (conad), small restaurants, greengrocers, bakery, .... the Vatican museum is 10min walk distance. the metro station (cipro) is just 5 minutes’ walk. from there you can go to piazza del popolo (station flaminio), or to Fontana Trevi (station Berberini) or to the city centre.
In general they were satisfied with their vacation stay in the flat except some point which could have been much better:
1. WIFI was not working during the whole week even so host was informed from day one. This was a source of frustration as it was not possible to access useful and sometimes necessary internet info
2. many practical tools and utensils are missing in the kitchen (microwave, small spoons, pasta drainer,...)
