If you're interested in history and culture, staying in areas like Jongno or Bukchon Hanok Village would be ideal. For a lively and bustling atmosphere, Hongdae or Gangnam might be more suitable. It's important to consider factors such as proximity to attractions, public transportation availability, nearby amenities like restaurants and shops, and the overall vibe of the neighborhood. Doing some research and reading about different neighborhoods will help you find the perfect location for your vacation rental in Seoul.
