It was small but enough for solo, since you won't be spending much time in the room anyway. I got lost at first but I always take Sinsa Exit 3, walk straight and turn left once you see a buidling with colourful 'hy' on it. It's a little uphill. There's 7-11, CU, Starbucks and Daiso nearby! There's also a shared kitchen and washer near the lift. Worth the money considering that you'll get your own toilet too (toilet and shower together, a little small but you'll make do with it!)
