We had a great stay in Napoli at Claudio's apartment. The apartment is perfectly located halfway between mainstation and old town, which are both in walking distance. Upon our arrival Claudio welcomed us personally and gave us heaps of information and tips on sightseeing and (really, really good) restaurants in the area.
The apartments' bedrooms were spacious and the beds comfortable, the bathroom equipped with modern appliances.
Last but not least, Claudio provided a complimentary cookie jar and if that isn't a killer argument I don't know what is ;)
