I finally tried booking a session through 오피스타 and honestly the Swedish massage at that little officetel spot was so worth it — just make sure you grab a reservation early because the evening slots fill up crazy fast!
I finally booked a spot at a 휴게텔 near my office for an aromatherapy session, but just a heads up — these places fill up fast since they run on reservations, so don't wait too long to book your slot!
