Seriously, you might think that studio apartments are expensive. Well, it's actually not! If you book directly from Korean Website itself, it would cost you like 50,000 won (S$59) per night onwards. Compared to hotels, which is minimum 80,000 won or higher (S$89 onwards) and it's a two star hotel, very little amenities and far from subway, etc.
After very much consideration, I've decided to settle with staying in a guesthouse. Considering since that I'm only gonna use the room to sleep and maybe watch TV. It' wont be that bad. But I'm kinda happy with the place I chose.-------> Yeha Guesthouse
It's situated near Insadong, the most cultural place in Seoul. Close to the ancient palaces. I reserved this room.
