In the old part of the city on a very lovely old building!
Apartment has everything you need and is quite large for 2 people. The only issue for me was the 5 sets of stairs as I have a bad knee atm! Would highly recommend this apartment for stays of any length in Naples!
We got lost trying to use Google Maps so stopped for a beer at a bar and they called us a cab which dropped us 20m or so from the room! Very handy when you have luggage!
