Great little unit right next to a busy street with lots of shops, food, etc! The door opens RIGHT onto a busy street that is active throughout most the day but pretty quiet at night. Inside the apartment you can hear the outside world but it's not too invasive :) Very comfortable bed, and functional utilities (though I really only used the small heater as I never figured out the stove. But there was a manual I did not read :D).
Internet works well, nothing spectacular but very functional! There was a heater Up and Down-Stairs which made sure everything was a nice temperature. As for the shower facilities, I enjoyed it! An actual shower head that held itself up was very nice, though I would have liked more water pressure.
I had some issues when I first arrived as the power was turned off in the unit, but the hosts were VERY helpful in getting it resolved! Super responsive and helpful hosts!
Something to note: Napoli is a VERY busy city and this unit is RIGHT in the middle of everything. Great location for closeness to attractions, but for me it was a bit overwhelming. Also had an issue with a police officer walking into the unit without knocking (door was shut but not locked as I was sitting right in front of it). This definitely made me a bit anxious and the authorities at the station were NO help AT ALL. Saying that the officer was working and it was fine and that they couldn't file a report since their translator wasn't in. So my issues are largely with the city itself. But the Air BnB was great!!! Definitely a refuge from the outside hustle and bustle (police officers barging inside not withstanding).
