The host Sebastian should have been honest with us about 2 things. One was saying he was 2hrs away from prague when he was actually in prague old town.
The really bad thing he did was remove the battery from the smoke and carbon monoxide detector. He knew the boiler was not working properly. Yet he still took the battery out. The alarm was the only thing that would have saved our lives if the boiler broke down and started leaking carbon monoxide.
