Apart from the anti-foreigner long-last presumption, Seoul has been proven as a friendly and smiley city for foreigner these days. Direction is written alphabet, annoucement has been made in Korean, English even other language like Japanese. I am sending you warm regards from Gwanak-gu, where one of Koreas prestigious education, Seoul National University is located, For students, you can spend this summer with your friends, having picnic in Gwanak Mountain or even mountain climbing/sightseeing 등산.
