Location, location, location - a great position, mid-way between all of the things we wanted to see. Perfect for a morning at St Peter's Basilica followed by an afternoon at the Capitoline Museum for instance. A great choice of restaurants in the nearby Campo di Fiori. We did quite a bit of self-catering, picking up lunch materials en route back to the apartment and having lunch there before heading back out to see the next thing. This apartment is just so conveniently located for all of the major visitor attractions.
