We stayed for 4 nights and had a good time. Even though Oia is a very touristy place, the cave house is away from everything but still close enough that you won’t have to climb too many stairs. The bell-boys and day-tour organiser were fantastic, they work hard! The bell boy made the carrying of suitcases very easy during check-in and check-out and the day-tour organiser (Gjo) helped us book an ATV and booked a great sunset cruise for us.
A few things disappointed us about the cave house but can easily be improved. We feel the cleaners could have given us fresh towels at least once - we had to use a towel each for 5 days. We also didn’t get any toilet paper refills - not fun when you run out and have to go all the way to the supermarket.
The coolest part of the house is the deepest cave-section in the back but it’s hardly used as the actual bed you sleep on isn’t in there. There’s just a futon kind of thing so we actually never even used that room at all...
