I was a long time resident of Busan but never really a visitor. I'll be in the city for a week or two and looking for a cheap motel. As long as the neighborhood isn't too bad and the rooms are bearable. I'll pretty much just be sleeping there. Any help would be appreciated. Thanks.
Re: Cheap Motels or Motel '촌' in or around Seomyon
You could try this one:

I stayed there for a couple of weeks while I was between apartments. It's foreigner friendly with English speaking desk and an English website - I think they also charge by the hour.
