I'll be back in Busan this week or next and need to find a safe, cheap place to stay while I search for an apartment near my new school in the PNU area.  I've lived in Busan before but have never had to search out temporary lodgings.

If you have any good recommendations I'd like to hear them.

Right now I'm strongly considering Lotte Goshitel in Seomyeon.

Ideally the place will be secure enough that I can leave my luggage there... but this is the norm, right?
