Once you're actually inside your room it's a great experience. The table is tiny so you will have to sit on the floor while using a laptop but it's otherwise very comfortable. The air conditioner is extremely effective, the place is perpetually quiet, the bed is good, the shower is good, it's generally a good experience. I have two things I didn't like, first is that despite the light load on the elevators, you'll often wait upwards of a minute for one to arrive at your floor due to how bad their software is -- and with how much walking I did every day it was never a good idea for me to take the stairs up to the 15th floor. The other is that the immediate surroundings of the building is the absolute worst area I found in all of 서울. There is no sidewalk so youre constantly leaning against buildings to let cars through, there's trash bags everywhere so it smells horrible, and worst of all you have to get significantly lucky to not have to walk by any smokers on your way in or out. Once you do make it through though, you're either in your room or you're in the lovely 서초 area depending on whether your starting or ending your day. Overall a good experience, especially for the price.
