We stayed in Luigi's apartment on what ended up being a very quick stop over in Napoli en route to Rome.
We were optimistically told that our drive from Bari via the Amalfi Coast to Napoli would be a few (4-5) hours, but after a quick lunch in minori and a few major failings by the Sat-Nav (due to a LOT of roadworks & re-routes) we landed in Napoli in time for rush hour traffic, and regrettably ended up being hours late to meet Luigi's mum. Nevertheless she greeted us smiling, showed us around (and any questions she couldn't answer, Luigi was completely available via SMS the whole time). She was so kind she held back rush hour traffic so that I could reverse down the road and take her car park in front of the apartment! (If you've ever driven in that city you'll know how that could be as equally traumatic as it was helpful!!)
Luigi's apartment was light, bright, spacious and clean. He has a great collection of Italian literature and Klimt prints. Bed was comfy enough, Shower was great, though not for tall people. Not safe for mobile toddlers if that matters too you - there's open stairs and windows.
Yes, no AC, and it's streetside, but I'm a light sleeper, but had no trouble sleeping with the windows closed and the fan on (mid-September) - the amazing meal and chianti at Il Castillo Trattoria/pizzeria might of helped too :)
Ps don't let me put you off driving in Italy, in the end I loved it - countryside was beautiful and didn't get a scratch on the rental car.
