Go ahead and book it! The room was nice and clean and about 15 minute walk from the city centre. The day we arrived, Beatrice informed us the air conditioning was not working (which was unfortunate considering the 30ºC+ degrees), but Linto provided a fan that was a life saver and also a map and keys to come and go as we pleased. The location felt very safe (from what I had read I had some concerns), even when returning from dinner at night with a child. I can't speak for the later hours, but the street is always very busy. If you have trouble sleeping, get some earplugs: Rome is very noisy with buses, honks and sirens 24/7 and this street is no exception. Breakfast was as advertised: coffee, croissants, yogurts and cereal - very decent. You can also leave your baggage in the kitchen after checking out if you have a late flight.
