The cave house is pretty newly renovated. Location is great - very central to all the iconic places you'd want to check out in Oia. The balcony has a great sunset caldera view. Only downside is that there's some construction going on near by it (but it wasn't noisy at all and didn't really impact our experience). Being so central, you are going to get some strangers walking past your cave house but it's not too bad and to be expected. While you can't drive to the place since the Oia village is only accessible by foot, they provided porter service which made check in and check out quite easy. They even arranged taxis for us which made our transfer pretty seamless. There was daily housekeeping service and breakfast as well. Pretty fast internet. Overall, made our stay in Oia super memorable and would highly recommend!
