The W Seoul, providing sweeping views from the slopes of Mount Acha, became Asia´s first W Hotel in 2004. The 253-room ultramodern hotel was designed by Aaron Tan, Tony Chi, and Studio Gaia. Its minimalist look is defined by round and oval furnishings, while bright-red accessories add exciting color accents. Don´t miss the 59- feet-long WooBar, the longest bar in Korea, serving 40 types of vodka. The Away Spa guarantees that nights of partying will be followed by hours of stillness.
