The location is superb and also the apartment is very nice: clean and very well equiped. It is not a quiet area though. Right across the little street there is a wine bar and amd several other bars and restaurants. Since their clients smoke, laugh and want to hang out and drink on the street it's is very noisy untill way passed midnight. But you can also join them, of course, if you wish.
For us the location was what mattered and the Colosseum and Forum Romano are at a couple of hunderd meters. So we had a good time.
