I grew Neapolitan last year in containers. I'm growing it this year in the ground with a shredded wood mulch. It's doing better this year, and ripening faster. The first ripe fruit was a while ago.
Here are some pictures of the fruits. I saved seeds from the three large ones in the bowl on 20 Aug 2019; those fruits aren't in the second picture. They tasted pretty good. They have a good sweet tang.
