KOTESOL 2018

As I am sure many of you know KOTESOL 2018 is being held at Sookmyung Women's University in October.

Address
(First Campus, Myungshin Building)
(100 Cheongpa-ro 47-gil), Yongsan-gu, Seoul, South Korea

I will be attending but have not been to Seoul (aside from transit at Inchon ) for 25+ years and that was only fir a week.

So I am poking about for a place to stay hotel ( and I have no idea what area would be best.

I am looking to be near the conference site (reasonable taxi fare and taxi time ) but do not want to be in the dead zone (or so it appears in area of the University)

The uni is a little south west of Seoul  station so I was thinking the area a bit Yo the north east (2-3 km away looked ok)   

I would like a reasonable priced hotel (70-89 usd) near where I can get some good Yakiniku and walk to a few shops.

Could anyone suggest a general area? Thank you.
