Found Ischia Review when I was stressing about getting my family of 7, including two young kids, from the Naples airport to Forio on the west side of Ischia late in the evening.
I got in touch for a quote - and Dion was very helpful and accommodating.
It was a maybe bit more expensive than arranging it myself but for the peace of mind it was absolutely worth it.
We were collected from the airport, taken to the ferry terminal and given tickets for the boat, then picked up at the Ischia port and driven to Forio, and the same on the way back.
All the drivers were very good and accommodating, we had a mix up with addresses (my fault) and they were helpful with finding the right place.
For larger parties and awkward connections I would absolutely recommend them. The website also came in handy for our stay, with lots of information about things on the island, sightseeing and amenities.
