Fabio was very nice. He explained us how to get to the place, met us at the flat and showed us around. At the day of our departure he came to take keys back at the time which was suitable for us.
The flat was clean (it seems like it is the only clean place in Napoli :-) ) and cozy and there were everything that we needed. It is small, but if you need a cozy place for sleeping, washing and having breakfest - this flat is for you.
The flat is very stylish, we liked it very much.
It is really near Napoli Centrale - it takes aroun 5-7 min walk, but at the same time, it is situated in a quiet lane, so nothing will disturb your dreams.
Also, there are some product shops and planty of restaurants nearby.

Thank you, Fabio!
