The Bluedome cave house was definitely one of the highlights of our family trip to Oia (two couples, a 7 year old boy and a baby). The view from the terrace was breathtaking and one of the best in all the island. The house itself had everything we needed, was comfortable and was full of style.
We unfortunately never got the chance to meet with Anna but she was very accommodating and always available, important since we had quite a few problems getting to the island due to strikes. In addition, a problem we had on arrival with the heater was quickly resolved.
To mention a couple of negative points, there is no wifi and also the shower is a bit tricky getting the temperature right. For us however these were minor details and by no means affected our stay.
We would definitely recommend the Bluedome cave house as a fantastic place for a family to stay in Oia. We will definitely try to stay there again if we return.
