It is a really nice place and the host is quick and efficient to resolve problems (if any should arise). The communication is very good. Olimpia was nice, the arrival and departure was smooth.
Just a tip for those who visit Rome in August. Don't wait for the bus. It might never come. This place is close to Quattro Venti, however, and the train and metros run regularly, keeping the time table. If you want to use public transport, I'd suggest taking the train and metro and going on foot.
