This is a lovely place in the heart of Napoli. The building is old, but the flat is new inside. the kitchen and bath are amazing! As others have said, it is part of an apartment and anytime someone enters the place, the door rattles. This is due to the building and can't be helped. Earplugs help with that.
The WiFi issue was only solved by the end of my stay but I hope they can solve it permanently for future guests. The WiFi numbers provided in the room did not match the actual wifi available in the overall apartment.
The building and the flat is well marked for finding it, and the entry with codes make for a seamless check in.
