The room we stayed in is part of a monumental Neapolitan building. You enter through a small door in a large door where a carriage used to pass through. Allessandro's building is on the top floor and is totally renovated, so very comfortable. Allessandro has left a number of historical ornaments intact. The roof terrace is really the biggest surprise of the house. It is very large, with an enormous table and a well-equipped kitchen on the same floor (which we were allowed to use by the host, as long as you keep everything clean).
The pant is in a side street of the old town so there is a lot of activity in the streets. There are many nice shops in the area and you can eat and drink everywhere. Moreover, almost everything is within walking distance or you can take public transport which is also very close.
So if you want to experience the real authentic Neapolitan city life, the property of Allessandro is really a recommendation and very affordable.
