Tina's is a party but is not the cheapest place to stay. You can rent a room with two beds in a private room at Sandy Lane for US$10. Tina's is a bed for one in a dorm room.
From there you can ask around and find a house for US$400 or so in that time frame.
Finding a good deal may depend on your choice of friends. Many young people make friends with the easiest guys to speak with. These are the hustlers and the landlords will shut you out of the good deals if you appear to be friends with that crowd.
Eventually you will have problems and home owners here don't want to sort that out anymore.
