Rena was super helpful and kind. Our Ferry arrival time in Santorini port was 3:50 am, it was not easy to find a place check-in at that time. Our cave had hosts that we could not check-in earlier. Rena was so kind to us that she provided her another cave which was right next to our cave. Rena kindly offered to us to stay free in there until our check-in time at 13pm. The hot tub was awesome, kids really enjoyed a lot in the bathroom. Expresso, cake, wine, water and snacks were thoughtful. A wonderful experience. Thanks a lot Rena.
