Jim I should have said: Cost of living is low in Korea EXCEPT for Seoul. If I were living in Seoul I would ask for more than the 2 millon a month, maybe 2.2 million.
Basic food costs are higher as are restaurants and cover-charges etc.
People in Seoul have the best manners and education but the pace of life, the crowds and the dust and pollution keep me away, even for a weekend holiday. Cheju, or Jeju Island in the south is beautiful, clean and subtropical with bird song, pineapples, orange trees and a volcanic mountain but feels a little isolated. One year would be good.
