How can I protect my rights when the air conditioner is broken and there is no hot water during my stay in the hotel?

If you know in advance that the air conditioner and water heater are broken during your stay in the hotel, you will be willing to stay. If the store does not explain and charges normally, you can ask for a replacement or refund.

When the air conditioner and water heater have problems at the same time, I think the hotel will definitely inform you in advance. If you continue to stay, it is personal consent. I think the store will definitely discount or reduce, and in this case, you can ask for a room change. Secondly, if the store does not inform in advance, you can call the consumer complaint hotline to complain and defend your rights.

Personally, I suggest that regular hotels notify in advance, which will satisfy the guests, otherwise their credibility will be lost.

I hope my answer can help you. I hope it can be adopted. Thank you.
