Yonsei University

My Goshiwon was small but it was just outside of Yonsei and located right by the subway (which is honestly your main source of transportation anywhere in Seoul aside from buses and taxi's coming home from long nights with friends if you didn't spend it in Sinchon)

There are many hasook-ships around Yonsei University. You pay anywhere from 300 to 500 dollars per month which includes home made meals, and laundry service. (Great! The International Dorm at Yonsei has no meal plan, and so when you stay at in a boarding house, you don't have to care about going out to restaurants for food. I like to have my space and freedom, and so boarding house is my choice. However, if it is your first time at Yonsei, stay in the dorm, and then look for a boarding house.

Although everybody had to get used to the quite small rooms and the fact that you even have to share them with a person you didn't know before, the I-House is a very good choice for 1st semester people. Of course you don't get too much privacy, but after all it's only for a semester and you shouldn't be staying in your room too much anyway ;-)

i didn't personally stay there, but when i visited people who did, the housing arrangement was nice. the rooms were smallish (as everything is in seoul) but there are communal tv rooms and kitchens.

The dorms are pretty small, kinda costly, and have no elevator either (at least not when I was there).

Other than having to share a dorm room, the dorm itself was clean with many useful facilities, including free use of washer/dryer, free internet access in the room or in the main lobby, along with well furnished community rooms on each floor.
