This apartment is amazingly well located, just off Piazza Venezia, in a secluded side street. Despite being so central, it is really quiet. Most sites are walkable and, if not there are plenty of bus options. Communication with Paola and her team was excellent.
My only criticism would be that, although apparently renovated only 2 years ago, the decor is looking pretty tatty - burns on the counters, grubby paintwork and stains on the marble floor.
Other than that, an excellent base for exploring Rome.
