To the hotel.

1. See if there is a ventilator in the bathroom for one year. If there is, as long as the noise is not too loud, it will always be on.

2. See if the hotel's fire prevention measures are perfect.

3. Is the emergency escape route clear?

4. The floor should not be too high.

Be careful, you can still live. But if there are windows, try to adjust them. Otherwise, I always feel uncomfortable and uneasy.
