If you are looking for something special, a place that is far from usual standard rooms/apartments and is different (and, to me, much better), then this is your place. Ideally located, this apartment is also a tango place, with very nice volumes, well decorated, a terrace with a view on Dante piazza, a kitchen, bathroom, and 2 very large rooms including the bedroom (and even a piano and a sound system play your music by Bluetooth); also a good internet quality. You can walk to the main places to visit in Napoli, like the very nice Via dei Tribunali, the Duomo, the port… If you have a car, recommend you park it outside (we used Quick, very reliable, near Porta Massa at the port) as the center is not allowed to cars without permit and you would not find a parking lot easily anyway.
The downside of being central is that you might have some street noise until about 10pm, when the main building door closes. But that is not so late and we really enjoyed being in the central live Napoli!
Luigi is very attentive to all requests and has good advice on things to do around. Apartment was clean, ready on time (we even got some extra complimentary time in the morning at check-in and in the afternoon 2 days after when checking-out).
