Hi, I'm travelling to South Korea end of March 2013 and spending my first two days alone in Seoul. I want to sightsee and relax while there before I travel to Busan to join my companion. I need advice on where to stay and what are the 'must see' things in the city. My interests are gardens, art, markets and local culture and I definitely want recommendations for a good massage/spa. I am on a relatively low budget but will spend when the product is worth it. Thanks.
