This apt has a GREAT location!! You open your door from this studio and you have this amazing view of Oia and the caldera! Same view from all the windows. And i do think it is one of the best and most unobstructed views. It is right off the footpath so it was a short walk anywhere including the Lotza Restaurant (which was very good food and good prices).
Other reviewers commented on the low water pressure and that is true. The hot water tank is so small that as you turn the water temp warmer there is less and less water that comes out. You only get a dribble if the sink is being used. Definitely not an island thing because our friends in 3 other homes (one a few doors down) all had normal water pressure.
The bread we got for breakfast was wonderful and there are markets nearby to buy some groceries. We got coffee to go from Lotza, which yummy and conveniently close.
For those who need hair dryers, one is provided with the apt! The cave house also had a good number of electrical outlets all over the room; very convenient. The mattress was firm. I didn't mind but it was too firm for my fiancee.
Overall, the view made any draw backs worth handling! I would recommend this cave house.
