I stayed here on business for two weeks and enjoyed my stay very much. The proprietors were kind and helpful, especially since I didn't speak Korean and they knew very little English. We were able to communicate using translation apps.
The hotel was very clean and I had no complaints at all. Amenities were light, but they did have free unlimited bottled water and canned drinks. Laundry service was also free. I dropped off clothes and they would be cleaned and returned to me the same day. My room also had a TV and access to streaming services such as Netflix. Interestingly, my room also had a gaming computer just like you'd find in one of the many internet cafes, but i didn't use it.
I only have one complaint, and it is that my bed was stiff and not very comfortable. From what I'm told this is normal for Koreans, and only large international hotels, which don't exist in Songtan, have the soft beds many Americans are accustomed to.
The location is good, only a short ten minute walk to the Songtan Entertainment District and Osan AB, but it is far enough away that you escape the weekend noise.
I anticipate traveling to this area for work periodically and would be happy to stay here again.
