This is a tough review to write. All the previous negative and positive reviews are correct. However, it doesn't deserve some of the low star ratings. It is a cross between a budget hotel and a modern hostel.
Location: Excellent. Walkable to 2 metro station (5-10 min walk). Anguk station is more straightforward, Jongno 3 Ga station is a little tricky, but after awhile, there is a quick short cut through the hanok alleys.
The hotel is also within walking distance to the palace area, including one that has free admission.
Pricing: Very reasonalbe.
Staff: Superb. The manager and other employees are responsive and extremely pleasant and courteous. I asked to switch to another available room, and it was done quickly.
Kitchen and common area: All of the machines and utensils typical of a very good hostel (much better than a regular hotel).
Room: On the smaller side. The floor is heated in the winter, and sometime it gets too warm. Rooms near the stairs are usually noisier than far away.
Bathroom quirks: Typical setting of an Asian wet bathroom. The shower head is position right above the sink and the toilet bowl. This didn't bother me.
The reason I think both previous negative and positive comments are correct is that, it has all the good services and amenities of a modern hostel. The private bathroom makes it a "hotel", albeit a budget one. The location, the services, the staff and the pricing all make up its quirks and drawbacks.
