After arranging an appointment, the host was 30 min late and without even excusing himself. He did not give any useful information, he just tried to sell us some tickets for a boat trip to Chrissi island. Later that same day, while showering, I realised that the water heater was leaking boiling water into the shower, as I was hit by very hot water drops (the heater is located right on top of the shower). I texted the host who did not answer. The next day we got out in the morning and when back, we realised that the shower was dirty and the water heater had been switched off. Someone had been in the house without us knowing! I find this behavior completely unacceptable.
