I've stayed at a couple different hotels in Seoul, particularly near City Hall. This is the best hotel I've stayed at in Seoul. It is a bit pricier than the others nearby but the service here is absolutely top notch. It is well worth your money if you have it to spare.
I've stayed here on business travel and everything is perfect. Yes, it is an old hotel. Your room will not be massive, and not everything will be brand new (although they did remodel recently), but you will be incredibly comfortable and can't really ask for more.
Breakfast buffet is the best and beats other nearby hotels out of the water. It is pricey if you pay separately (last time it was just shy of 50USD). Room service is phenomenal, front desk, concierge--everyone is so friendly.
The only downside is the location. Yes, it is located near City Hall and in the center of the city, but the entrance to the Westin is very awkward and so it is a strange walk to get anywhere (i.e., subway, restaurants).More
