A motel is usually smaller than a hotel. A typical motel has or one or two floors and visitors can enter their room directly from the parking lot.

I would suggest using "trouble" instead of "problem".I think the best way to say it would be: Those people had caused a lot of trouble. Those people had been a lot of trouble.
