Hello dear aspirant

Hope you’re doing well

A lot of Delhi university colleges have their own hostels for boys and girls separately. The list of DU colleges having their own hostel is-
Miranda House.
Hindu College.
Hansraj College.
Ramjas College.
st stephens
sri venkateshvara.

These hostels have less seats. If you dont get into one of these then there are lots of private hostels near every du college be it on campus or off campus. Those private hostels are also good and safe.

The fees of hostels are around 8000-10,000 a month. It depends on hostel to hostel.
Private hostels take the fee monthly whereas colleges take total fee of 1 semester together.

Hope this helps

All the best
