All places in Oia require you walking many steps. Think about yourself realistically. There are places closer to Main Street. This one is 8 floors down from everything you’re going to want to visit (including meals).
All that said, this place is AWESOME! Rena made the trip so effortless and the jams, bread, coffee, and other snacks came in so handy when I didn’t want to walk 8 floors up for lunch.
Overall, this location is so peaceful and quiet and the whole cave was awesome.
