We booked our room through a b&b reservation site, which had very good reviews on Cristiano's Vacanze Romane. Our expectations weren't defrauded.
We stayed in the red room, the one who has inside private bathroom, every room has a different colour and different type, as you may check on his website (too bad i couldn't find it previous to my reservaton, it's very simple and precise). The room is very nice, it has a fridge, tv and a fan, space and Cristiano still offers wi-fi internet. The bed is very comfortable.
Cristiano is a very nice guy, he was always helpful and prepares you a home made breakfast good enough to start your journey in Rome.
One of the things that will stay in my vacation memories is the old-fashion elevator, those kind of things you won't surely find at any hotel. Really a must!
Depending on what you may want for your vacation in Rome, it can be really a great location to stay. It's in a calm and quiet area, near S. Giovanni metro station and S. Giovanni Church. From here you can easily walk to the colosseum, termini station (where you can catch the train to the airport, metro and the hop on hop off buses (beware of the A110 line if it rains!) and it takes you about 10 minutes.
Nearby, in Via Emanuelle Filiberto, next to the shoe shop there's a café which makes you a very good espresso, for what we paid 0,70 eur each.
Intending to return to Rome, it'll be definetely where we going to stay! Thanks Cristiano!
