It was a great choice. The hosts were extremely welcoming and provided exceptional experience. They answered all our questions about the area, attractions, ways to arrive from/to the airport.
The apartment itself is very cosy, nice and clean. You can cook if you want.
The location is very good, 5 min walk from Vatican, 30 min walk from the center (and its very nice to walk!), 2 min from the metro station.
There are a lot of cafes around the corner.
