Looking for recommendations on an island to stop/stay for 2-3 notes between Santorini and my return to Greece. Will be spending 5 nites in Santorini at the start and then want to ferry to one (POSSIBLY 2) additional islands for 2-3 notes before returning to Athens for my final nite or two.
Don't want to rent a car.
Want to be able to walk to the beach.
Prefer quiet to clubbing
Appreciate all the help! Thank you.
