two 21 year old girls looking for a cheap acommodation in South Korea, Seoul, Jongno-gu

Hello! My friend and I just got a 100% tuition waiver scholarship for internation semester summer program of Sungkyunkwan University , Jongno-gu. We will stay there 1 month , from June 24th to July 23rd. However, the dormitory fee of school is quite expensive,which is about 650000 KRW and the students like us cannot really afford such a price. Therefore, we are still looking for a place that has a room for 2 people to live. We will share the room with each other. I want the room that is both comfortable but its price is affordable as well because we are just students . Moreover, the time we spend at home is less than at school so the fee of our staying is not much. If any of you has the room like this, please announce me. I do really appreciate your help.

Many thanks and best regards.
