The room is well located and easy to reach from the main train station, Napoli Centrale. The station is also the pick up and drop off point for the Alibus which you can get to or from the airport on. The station is also the starting point for any visits to Pompeii. There are several supermarkets and fast food outlets and on the other side of the piazza garibaldi are a few restaurants. Antonella is an excellent host and will provide a map and recommendations if you require this. The room itself is very spacious, the shower was wonderful and the added touch of a personal fridge already stocked with water, juice, milk, and fruit was very welcome. In the communal areas there was a coffee machine and breakfast foods. The room is on the 4th floor, which can be accessed by a lift but requires 10 cent coin to operate, we only ever got one coin in our entire stay!
The only downside was that to reach the building from the station google maps took us the shortest route which was past the street vendors, groups of intimidating youths and of course pick pockets which we actually Witnessed first hand, I would suggest leaving the station or bus stop and going left and around the piazza thus circumnavigating the said youths and pick pockets. Hold on tight to your phone, check your bag is closed and just be aware of your surroundings and you should be ok!
