One time my roommate needed the house alone when their girlfriend was visiting. So I went to stay in a hostel for the first time in my life.
It was a very fun experience that I think everyone should try a few times in their life, especially when travelling in a foreign country.
The boys and girls were officially separated into different sides of the Hostel to sleep, but of course, after midnight people don't really listen to the rules...
So yeah, I fully understand this sign, and I have already made my reservation at the SRKR Engineering College Hostels.
