Giovanni's place was very comfortable for a two night stay. It's conveniently located in the Spanish quarter, but it's a bit of an uphill walk to get there, and then three very steep flights of stairs, with no elevator. The room has a really really comfy bed and an A/C for great sleep. The downside was that the washroom was very poorly stocked, without even handwash and just a couple of sachets of shampoo. It feels more like a hotel room, since there was no kettle/coffeemaker, so you'll have to get water and coffee from outside, which should be fine since you're in Naples. But for a short stay, Giovanni's place was perfect.
