We're on a quad bike now. It's more safe, because of the pot holes.
If anyone is going, you need to find the restaurant called metaxi mas on the island. It's not in a touristy spot at all, best food, amazing view. And fairly cheap for the island.
Oia has too many crap restaurants, and over priced... Do some research or eat else where.
We ate at a cozy place called Penelope's, owned by an old man and his wife. They were the funniest characters we met on the island.
I went diving with mediterrianian dive club. They were all really sweet people, but the equipment was older, and their team is small. If you have open water divers on board your most likely not going any farther than one location.
The night dive was fantastic though.
We stayed at Ira apartments. It's nice that it's off the main road so the pool is quiet.
