The out of town location was no problem and provided great views of the city from not only the hotel but also the easily accessible mountain walk nearby (if you have an hour or two). The service was world class and food also very good. Costs - seems like all Seoul (top) hotels and branded shops, malls and department stores were at least as expensive as Europe. However, Seoul itself is good value in respect of taxis, subway, restaurants, basic shopping, tourism etc.
