I booked this hotel through Venere.com, and been to Rome between 24th - 29th May 2007. Our Italy trip started from Milan first (for 2 days), and Rome was our last stop. We selected this b&b because of the comments in this site. Overall it was a great experience.
We flied with Ryanair and our flight was delayed, by the time we arrived at the Rome airport it was already 12am, and the owner of this b&b contacted us asking whether we needed a taxi back to b&b or not, and offer us a reasonable price for the taxi fare.
We were given breakfast vouchers for 4 days (sunday no breakfast), which was in a cafe shop (walking distance - 5 mins from the b&b). The b&b was actually an apartment with 3 rooms + 1 office room + 1 toilet. The lift was a bit old fashion. Water, coffee machine, and fridge were provided in the shared area. The toilet (with shower) was clean, bright, modern and big. Inside the room, there's a shared balcony, TV, big fan, WIFI internet, and wardrobe. The nearest metro station (Re di Roma) is just 5-8 mins walk. There are many shops around the area.
PS: Don't expect to have big breakfast in McDonald's, they just provide bread and coffee in the morning.
