Rena was great to communicate with; always prompt and helpful. She organized the driver to pick us up (at a fee), and the a porter was waiting to carry our luggage (trust me, you don't want to carry it yourself down the many winding stairs) and led us to the cave house. Rena was waiting and showed us the 2 bottles of wine and cake for our welcome and made sure we were settled in. The location is perfect if you want a little quiet but still really close to everything in Oia. We never walked more than 10 minutes to get anywhere, and the cave house itself is so cute and cosy. We had 2 terraces which are awesome for enjoying your breakfast with a view or just sunbaking. Would definitely recommend this place, especially for the price and if we ever came back it would be to stay here.
