I stayed in a hotel last night. In the middle of the night, a strange woman knocked at the door and asked if I needed it. Should I call the police?

It's okay to call the police, but it depends on who it is.

If a stranger knocks on the door on purpose, it is very annoying. Of course, you can call the police. There should be no legal responsibility.

It is recommended to find evidence to call the police. Police comrades are also very hard at ordinary times. Don't call the police out of thin air
