A 10 minute walk to Yong-san station, very nice staff, delicious breakfast, close to a grocery shop and ATM in the nearby connected hotel. Nearby shops open between 9 and 10 am

Price was a bit much. They were inconsistent with a promise they made when we checked in, so you shouldn’t trust their every word. 

Apartment was very quiet, clean and spacious. Bathroom has under the floor heating as well as toilet seats. The shampoo, conditioner, body wash, moisturiser are specially made for the guests and it was really nice. Bedsheets get changed every day. The gym facility was excellent. The 3rd floor restaurant has a good ambiance and food was really good. The breakfast is good. I have stayed 2 weeks and the hotel staff was very kind and professional.

Maybe the restaurant can add more items to the dinner menu.

Central location, away from traffic, congestion, and frequent protest demonstrations. Mall/grocery nearby. Convenience store and restaurants in Novotel next door. Our unit had 2 bedrooms and 2 full bathrooms, as well as a kitchen and office. Very spacious, nicely appointed, quiet rooms, comfortable beds, very clean and modern, service was good, very nice gym.

Construction made access to mall more difficult, but otherwise, location is central and easy to access all of Seoul by cab or subway. We did request extra blankets, but they said they didn’t have any available (?). They did supply some extra sheets.

The location is ideal, right next to Yongsan station, so very easy to get the Metro. The room was fantastic, the staff were excellent, this was the second time we have been in this four hotel complex, and the Grand Mercure is better than both Nova's and the Ibis. Highly recommend this place.

Nothing

The room was amazing. Lovely big bath and shower, kitchen area with washer/dryer and washing liquid included. Instructions for using appliances in English. Room service food was nice. Nice view over the city (although booking.com said river view which we didn’t have). We unfortunately didn’t get a chance to check out the pool or roof garden but both sounded great.

It was a bit far and difficult to come from the train. to be fair, I think it is normally easier but the station exit is having work done so dragging luggage up and down a thin slope with uneven ground wasn’t easy. Not the fault of the hotel but definitely affected our stay. Also a bit out of the way in general and difficult to find food options outside of the hotel, especially at night eg 9pm.

Modern room, elegant, everything was beautiful! Food was great! My mushroom soup was definitely from a high-end restaurant (room service) b/c it tasted sooo gooood!!!!!

Taxi drivers had a hard time finding this hotel bc it looks fairly new.

Everything was clean, and the room was spacious with literally everything you need! The staff was very kind, and the breakfest was super rich!

The location was nice, it's more suitable for someone who looks for a more quiet area. However, to get to the main attractions of Seoul, you'll need public transportation (which is about 7 min walk from the hotel)

The facilities in our room

We were not allowed to extend our check out for 2 hrs later than the usual check out time.

Comfortably sized, well appointed Suite. Good housekeeping, nice touch to provide detergent and dishwasher liquid. Efficient and helpful Front Office. Good choice at breakfast. Five minute walk to Yongsan subway/train station.

At $500+ per night, a bit pricey for its location and facilities. Not near any significant monument/area of visitor interest. Not many dining options in close proximity

The room is a little bigger than the others in Seoul. All the facilities in the room made our stay very comfortable. A variety of breakfast buffet was great. Every morning they served the slightly different food so that we really enjoyed the meals during our stay.

We stayed in this hotel for a week and hoped to get a room which is in the high-rise, but the long term guests had already occupied the most of higher floors because they also offer a residential hotel services.
