The cave house is very unique and well decorated, kitchen is well equipped as well. The landlord Kostas is helpful, he waited for us in front of the house when we arrived and later passed by again to tell me where to go &eat. I had good time in Santorini with the accommodation. But there is one thing to mention, we met Kostas in a restaurant one day before we left to Rome, he asked us to leave the key inside the house and keep the house unlocked when leave, I thought it's risky so suggested lock the house and put the key in the yard but he said no need to worry. I thought maybe Santorini is safe island. Later in the midnight Kostas wrote message in Airbnb and asked me to make sure all doors locked and leave the key outside the house in some secret place before leave. But at that time we already fell in sleep and had very early flight in the morning, so I had no chance to check Airbnb message, and Kostas knew the time of my flight. Then when we landed in Rome I saw the airbnb message, Kostas also asked if I locked the door and put the key in the right place. I replied back and checked if there is any problem, but no reply by far, anyway I hope nothing got stolen, also kindly remind guests who stay here next time to double confirm with the landlord. It's better to give the instructions earlier rather than sending airbnb messages in the midnight right before u leave
