We had a good experience at Danilo's place, though we were only there for a couple hours. It's a pretty good spot to crash before or after a flight.
The value for money was for sure better than most of the other options, and for that reason I would book again if needed.
The alternatives around those prices in Nápoles are not too good, and this apartment gets the job done. I can't say I felt at home but that's also not what we were looking for.
I think it would be in everyone's best interest to mention that the primary bed is actually a couch that turns into a bed (it's already open and made when you get there). This was not clear on the ad and it seems like a detail I would add. The mattress is comfortable, but I'm 1,77cm tall and I could barely fit. Just something to keep in mind.
Thank you, Luciano.
