All the differences between smoking rooms and non-smoking rooms in hotels.

If there are smoking and non-smoking rooms, the hotel reservation page will let you choose. The hotel's own rooms are not within the scope of non-smoking stipulated by some countries and places, but now most hotels will directly write non-smoking rooms on the reservation introduction page, that is, smoking is completely prohibited. In addition, the smoking room often smells like old cigarettes. If you don't smoke, you can choose a non-smoking room or stay in a completely smoke-free hotel.
