Female students most of the time are confused about there stay duing electives in shifa. Students from other cities better find there accomodation in islamabad before coming for electives.
There are two options

1. Talk to students affair office at shifa for hostel accomodation in shifa's female girls hostel.
2. There are female hostels in sector I-8 which is near to shifa better talk to them. There are hostels in I-8/4

Better ask about the hostel charges for shifa's female girls hostel and private girls hostel.
