Let's get something out of the way, if you want something in a convenient location (close to the center) in Naples, the surrounding area it's not gonna be pretty. That being said, I spent a few nights at Bruno's, never felt unsafe and the environment seemed clean and organized, just not as pretty as Vomero.
As for the experience inside, I arrived way earlier than check in time and asked to leave my luggage at the counter so I could spend some time in the city, well, they checked and my room was ready so they just let me have a free early check in (around 9:30 AM).
I always left the B&B around 9 AM (after breakfast) which was prepared every day by Giuseppe's mother, she's very kind and if there's something she doesn't understand she'll whip her phone out and use a translator app. Every day I had a sfogliatella and croissant, cappuccino, juice and an omelette with a toast.
When I came back every day my room was made and tidy, they even organized my toiletries which I know I left quite messy the first day. The room is spacious, bed and pillows comfortable and the A/C works wonderfully.
Lastly, Giuseppe's mother ordered me a taxi when I was running tight on time for my train since she said I'd have a difficult time getting a taxi any other way in a sunday morning.
Thanks for everything during my stay.
