Recomendations on hotel in Seoul?

I'm going to Seoul soon for a trip and was curious where to stay that is a short distance to a lot of fun to have.
anywhere in the Gangnam area or Myeondong district. most if not all providers can come to your hotel with no issues and from my personal experience the girls incalls are usually in either one of the area i suggested. Myeondong has the most affordable hotels also. good luck and happy endings. be sure to post up your experience.
Do you know reputable agencies to contact?
