The BnB really is situated nel cuore di Napoli. Just turning into the narrow street where the flat is located is an experience :)
It is also close to the main train station (15 minutes by foot) and just around the corner from the old town (cathedral). There are a lot of bars and restaurants in that area.
The BnB is very clean and has the typical italien breakfast. The single room is very small, but who is in Napoli to stay in the room...
Antonio is a very friendly guy who quieckly answered the messages and he has also good tips for getting the best Pizza ;)
