Adults only
Good for just sleeping.
Clean for the price, and the staff are friendly. - What was good: The powder room had skin lotion as well as a hair dryer, hair iron, and amenities (toothpaste and toothbrush, flat comb, hair ties, cotton swabs, cotton pads) — they were simply provided without a per-person limit, so use them responsibly. There is a water dispenser on each floor. At check-in they provide a shower bag (you must leave it when checking out), two towels, and disposable slippers. Inside the cabin there were light switches both by the door and inside, there were hangers, and in the lobby you can eat low-odor food and work on a laptop. - Notes: It is similar to a capsule hotel, so rooms are not soundproof, rooms are small, and the shower is a shared facility. (The shower stalls are fully enclosed, so you won't see each other's naked bodies!) Be considerate, keep quiet in the rooms, and tidy up after using the shower. - Personal items to bring (optional): earplugs if you are sensitive to noise, shower towel, brush, toothpaste (there is an amenity but it is hard to open and the amount is small), other cleansing products (there is facial cleanser), etc...

I stayed alone for work nearby; it was very clean and comfortable.
Great place for solo travelers.
At a cost-effective price, the service and amenities feel like a hotel, so I use it every time. They provided almost everything including shampoo, conditioner, body wash, toothpaste, toothbrush, razor, shaving cream, cotton swabs, and a hair dryer, so it was excellent. The earplugs and eye mask were also useful for a good night's sleep, and the bedroom was clean and quietly maintained, so I was very satisfied.
I stayed here again because it is such a great place to stay alone in Gangnam! The amenities like toothbrush, hair dryer, razor, shampoo, and conditioner were so neatly provided that it was very convenient and nice. I will use it again next time!
Everything was clean and well kept. If I'm alone, I think this would be very useful for a last-minute stay.
