Host was not there when we arrived, and did not leave any instructions on how to use anything. The heat and hot water had been turned off. We have absolutely no clue how to turn them on - they are totally different from the systems in our country. We had a few hours to shower, sleep, and leave again for the airport. Hours after emailing the host, she replied that her friend forgot to turn the heat and hot water on on, to use the shower in her own bathroom, and "Sorry for the inconvenience."
