Do remember to check the closing time if you stay in a hostel. If you are late back to the hostel, you will be in trouble. I had this experience. My friend and I tried to find a hourly room along the street, no one gave us the offer coz they suspected we were lespians who wanted to rent a room for 'that'! Then, we just sat in a coffee shop overnight. And there are not too many coffee shops run overnight. Funny!
