We stayed six nights in the apartment - 2 adults and a teenager. Perfect for our usage. Nice living room, full kitchen, and plenty of beds. The decor is beautiful and very memorable.
The neighbourhood is close to Piazzale Roma and the busses, and close to the more touristy parts of the city - but the area surrounding the apartment is quiet and nice. Supermarket just around the corner, cheap (and really nice) restaurants and a nice homely vibe.
