Pros: The view, working wifi.

Cons:
1. The stairs (there's a lot, wouldn't recommend it if there's an elderly person or unfit person in your group - there is also no assistance in getting your suitcases here so bring a backpack or get ready for some cardio. There are donkeys and people who help but the host didn't tell us about this option).
2. The humidity (its a cave with a teeny tiny humidity machine thats supposed to work.. i think. Everyone wakes up wet with sticky wet sheets stuck on them and my cousin and I are both asthmatic so got coughs going)
3. The lack of basics (toilet paper, soap, shampoo, conditioner, salt. After I sent the host a message about it she did send toilet paper and hand soap. Sharing a regular bottle of hand soap between 6 adults was interesting.)
4. The failing electrical ( lights went out for about an hour our last night. I would have mentioned it to the host, but there was no wifi and with no working phone line in the cave.. no one to reach)
5. The doorknob which kept falling off (at one point we had to climb thru the window because the cave is literally falling apart)
6. Check in (Being met by an obviously intoxicated gentleman named Nick, and being told off for making him wait. I apologized before hand and once again when we arrived and thanked him again when he checked us in for being so kind as to wait for us until 2am, I mean as an airbnb host I get it, its annoying. But you don't tell your guest "waiting for you has been terrible, you've ruined my night."
7. Broken furniture and dead plants. The picture depicts this beautiful terrace, in reality all but 2 chairs where in proper working condition, the umbrella wouldn't open and there were only 2 pots of half dead flowers.
8. Shower. The photo depicts a shower head that stays up but it was broken so we were left showering by holding the shower head the entire time. Not the worst thing in the world just uncomfortable when washing hair.

Synopsis:
If you are an adventurous young group who don't mind overpaying for truly gorgeous views, this is the place. However if you don't feels like paying such exuberant amount for a less than 4 star experience, or have any sense to research other locations, pass. It would also be easier to stay in Fira and taken the bus to Oia. Much more to do in Fira and easier commute. Being in Oia is great if you want to feel more secluded, alone, or maybe a honeymooner, or maybe you're just into unnecessary bus trips, or you've rented a car for the entirety of your stay. Fira (the center) is where you would take another bus anywhere else, or do any real shopping, dining, clubbing, activities, rent a car, rent an atv, etc.

Hope this helps.
