Our stay was amazing! We liked that the home was authentic, but very comfortable, and perfectly situated outside the main city of Oia to be more peaceful away from crowds. It's about a 15-20 min walk at a modest pace to what I considered the "start" of Oia. It was also a pretty easy walk down a trail to get to a winery (15 mins). There are few couple good restaurants that are a 2-5 min walk which we enjoyed. One thing to note is that there is some walking with a few stairs and minor "hills" involved with staying in this home since the village does not allow cars.
The private pool can be set up as either a hot tub or plunge pool for cooling off while enjoying the views (note, not caldera side but the views are very pleasant - the fields and the sea). In the pictures, Cave House II is the one on the right side with the pool and sunbeds on the same level.
The hosts were very helpful with setting up our transfers and helping with our luggage. They also provided recommendations on restaurants and activities. My only regret is that we didn't stay longer!
