We had a lovely stay at Fabrizio's apartment. The apartment is about five minutes' walk from Napoli Centrale station, from where you can easily catch the metro to get around the city, or take an inter-city train to further destinations. There's a good-sized supermarket two minutes' walk away which is very handy.
The apartment itself was clean and comfortable with all the amenities we needed. The bed is huge - definitely bigger than a double - so we slept really comfortably; the bedroom can get warm, but there's a fan as well as air conditioning so you have good control over the temperature. The only thing I would say is that if you're tall, watch out for the low ceilings in the bedroom, kitchen and bathroom!
The apartment is on the third floor, and there are a lot of stairs to climb, so if you have any mobility problems this might not be the place for you.
We were greeted by Anna on our arrival, who gave us lots of tips about the area and how to get around Naples. Communication from Fabrizio was great throughout our stay. Overall, a lovely stay, and great value for money.
