The studio flat is in a great location within walking distance to so much including the metro, which will bring you anywhere else you'd like to go. The flat is modern and clean and the hosts respond quickly and are very helpful.
The downside beyond the hosts' control is sometimes people outside can be a bit loud but the windows in the flat block a good amount of that out so they've done what they can to avoid noise issues.
I'd definitely recommend staying here if you're in Naples!
