Furnished Weolse 1BR Apartments?

Is there such thing as furnished 1 bedroom apartments? Planning to move to Korea for one year so I'd prefer furnished apartments (no co-living) and ideally 1 bedroom in Seoul.

My budget is somewhat flexible so I can provide a deposit up to 20M won.

I'll probably book an airbnb for a couple weeks so I can tour places with an agent before I settle down to one place but I was wondering if furnished weolse is even a thing.
