I had a nice and comfortable stay there at their place. Everything was organised to put the guest at their ease. the room is spacious, specially for me that I was alone. the bathroom was the best part....very authentic, clean, new and l can say much better than a 5-star hotel.
Whenever I needed something more or some information, suggestions and so on....Carolina and Marcella were there for me. in the neighbourhood there are every kind of shops, a bus stop and even a metro stop. remember Via Gesu e Maria, that will be a nice short cut to Via Toledo and down town area, I don't reveal you other short cuts, cos whenever you discover one you fill as a champion, so I let you experience it as well :-)
The only thing is the fact that Naples is not like the other cities, you need to dress as you go for a trekking if you want to see everywhere on foot. backpackers are the winner, trailing the luggage almost killed me as the sidewalks are mainly stone pavements, but that was my mistake. There are a lot of beautiful things and new experiences in Naples that you can't leave it without a small on your face. The stay at Carolina and Marcella's apartment is an added value by sure, I'll get back to them 100% :-)
Enjoy your trip!
