Stayed at the Bellini house for 5 nights. I second all the other guests excellent reviews. It is well organized and equipped. Roberto and Federica were very helpful and responsive. It is nicely decorated, has all the needed facilities, and is a great place from which to explore amazing Naples.
I stayed at one of the rooms that are not facing the garden, and right next to the reception and breakfast area. It is a nice room and has a comfortable bed.
Breakfast is self prepared, and is good. There is a honesty box for soft drinks and water. Roberto was very helpful about ordering a taxi, at a fixed rate, to the airport.
The last night I stayed at the room facing the front of the building, and at night time enjoyed the drummers circle that convened at piazza Bellini.
The Bellini house is a great place to stay in Naples, and is highly recommended.
For future booking, I would ask in advance, what is the noise level, in decibels, at the room that I would be staying at and if the drummers circle is planning a all night gathering at the piazza below.
