TLDR: well situated hotel near major attractions, shopping and restaurant streets, and near 3 subway lines. TINY room (photo makes it looks way bigger) and no elevator, but with amenities such as mini frig, microwave and washer (no dryer).
The hotel is within 2 to 3 subway station hop to the famous palaces and a tradition market. At night the ENTIRE street turn into outdoor hangout popup vendors for drinking and eating.
The location is central North Seoul. Subway to east, west or south locations takes about an hour if crossing or near han river. Keep in mind if you don't plan to switch hotel and visit those areas. Hotel is also near the Cheonggyecheon stream for morning and or evening walk.
The Room has useful amenities: mini frig, Microwave, Washer (Super useful!) and quick and cold AC. but its TINY; if you are not careful, you'll likely hit your toes on a furniture. No elevators and small stair way, give you a workout if you are not active. A small basement with free water, coffee machine, bigger frig, freezer, a washing machine and dryer, a electric cooking top, all useful if you are tired out by site seeing and just want to order in.
All in all, depends on your needs, can be a workable compromise.
