The apartment is on a busy street, so it's a bit noisy at all times of day and night, but is very convenient for the main railway station at which we arrived and for the historic centre of Naples. Furnishings are magnificent and the bedrooms were all comfortable
It was easy to walk into the historic centre, and to the station to get to Pompeii (half an hour by train) and Herculaneum and Vesuvius. (The latter can be visited in a day, though in winter, with short days, you need to plan timings carefully)
Car hire was available at the station and cars are collected from a large underground car park in front of the main station.
