An Unmarried couple on work tour sharing a hotel room in Islamabad, Pakistan. Any problems?

Are there going to be any legal illegal or whatsoever problems for us to book a hotel room in Islamabad, Pakistan? We would probably be booking a 3+ star hotel. And also you guys can suggest a place.
Serious answers from experienced people are needed.
