Hotel Atrium is an average hotel. The room was very basic and includes the bare minimum like beds, a washroom, and a mini fridge. It was also clean but you could tell the hotel has been around as the carpets have visible stain spots. There’s also a subtle scent but nothing too bothersome. The main winning point for the room is how spacious it is. Location is decent. It’s right next to Gwangjang Market. Luckily public transportation in Seoul is very advanced so bussing and subway made it easy to get to different parts of the city.

This hotel is in a good location - close enough to get to palaces, shops and restaurants but far enough away from the tourist hot spots to feel special. Nearby are plenty of all the amenities you could need. The hotel is modern and clean, the staff are very helpful. Our corner room was spacious and clean. The bed was huge!

Clean room, excellent water pressure, friendly and helpful staff who answered my questions via app, location is near Myeongdong. However we returned to one particular Korean BBQ restaurant a few minutes walk from the hotel. Laundry in the basement gave clear instructions on how to operate macines and how to pay.

⭐⭐ Disappointing Stay – Hotel Needs Major Updates Unfortunately, our stay was well below average. The rooms were outdated, with terrible, worn-out furniture that made it feel more like a one-star hotel. The entire hotel is in desperate need of renovation and modernization. The location was okay, but the service was very disappointing. We had a lot of luggage and asked the reception staff for assistance. Instead of helping, they laughed and spoke among themselves in Korean, which felt extremely rude and unprofessional. Overall, a disappointing experience. The hotel definitely needs improvements in both its facilities and customer service.

Fairmont Hotel experience has always been fantastic including this one. It was a little surprising to see that the shower head was old and rusty, and was not spraying properly. It’s not a big deal but a minor detail.
