There’s a reason this is my hotel of choice for Seoul trips, for over ten years and counting. The facilities and rooms are definitely a bit worn, I admit. But the staff, service, and convenience are so stellar that I continue to stay here.
There is a fully equipped kitchen with cookware, dishes and cutleries. An in-room washer means I can do laundry frequently and the closet has a built in clothes drying rack (or you can request a larger drying rack to be sent to your room).
A large grocery store is two blocks away and they will deliver your purchases to your room - you shop at the store and let them know it is the Artnouveau + your room number. No lugging groceries back, it’s free delivery, and you pick out your own supplies.
Fantastic restaurants all around you, super close to subway and bus stops, a 24 hour convenience store next to the hotel.
A separate living room and bedroom area in even the smallest rooms is nice. This hotel has huge rooms - larger than most other hotels I’ve stayed at for a fraction of the price.
