Overall, our experience was a good one. The location is great, the hot tub is a nice bonus and Zaf was amazing. The only downside which has nothing to do with either Haris or Zaf is the lack of respect other tourists have for private property. We witnessed people stepping over gates and climbing into other people's patios just for the sake of taking pictures. Multiple times we asked people to leave "our area", most did without any issues while a couple made a stink about it. Talking with others in the area, this is super common and just a by-product of the way the cave homes are laid out and the labyrinth that is the walkways. I certainly wouldn't allow any of this from keeping me from staying in Oia again, knowing so would just better prepare me for what to expect.
