Renting a single room costs 500+ a month.
Two rooms are about the same 1000.
At present, heating is generally one valve per household.
If you are only an intern, it is not necessary to be so close to the central hospital. I suggest that you rent a house near Martyrs Mountain, and sharing it with more reliable people can also save some money.
You'd better ask if there is a single dormitory in the central hospital, preferably.
