On a business trip to Korea earlier this year, I stayed at the Renaissance Seoul Hotel in Yeoksam-dong, which is part of the Gangnam district. You've probably heard of Gangnam from Korean rapper Psy popularizing it in his 'Gangnam Style' music video. The hotel is about 1.5 stations away from Gangnam station, and is a terrific location in Seoul. You can spend like 15 minutes and walk to the nearby Seolleung-Jeongneung Royal Tombs, which is part of a UNESCO World Heritage Site and a nice stroll.
I took this photo from my hotel room, the morning before my flight back to the US. The colors, while still vibrant, are a bit muted due to the rain showers that day. There's something very futuristic about looking out your window and seeing a never-ending sea of buildings.
Prominently shown in this photo is the Choong Hyun Presbyterian Church. If you look to the mountain in the distance, you can make out the faint outline of N Seoul Tower, which is one of those observation towers popularly found in large Asian cities.
