There was en early May heat wave during my three day stay in Strasburg, with temps topping 30C. Good thing i booked a hotel with air conditioning, right? Nope. The guy at reception said rhe hotel AC was switched to heating, and because the heat wave was forecast to be over on three days, they werent going to swith it to cool - I should just open the window. Well, it's 30C out, so I don't see how that would help. Now I don't know what switching the whole AC system to 'cool' entails, but unless they'd have to send someone with an ice ax to the frozen tundra to retrieve ice for the AC, i dont get how they can justify making their guests so uncomfortable for the entirety of their stay.
