I was a tour leader of a group of 30 people and we stayed here for 8 nights in September. The hotel is close to Euljiro 3 metro line (lines 2 and 3), 1 minute walk from exit 1. Front desk was friendly and always available to our requests. My room was on the 15th floor, not very large but nicely decorated, quiet with very good wifi connection. Coffee and tea are in the room as well as 2 bottles of natural water free.
One downside is the lack of laundry service even though there is a room with a washing machine and ironing board, but all this takes precious time!
All in all, I think it's a good accomodation for those who do not have super pretensions and will gladly come back.
