Our stay at Nine Tree was excellent. At first, the Junior Double was too tiny for two people. It might be just spacious for one person. We had to upgrade to double twin which was much more spacious for two people. The hotel was so accommodating and our room was upgraded with no extra charge with a better view to the park. Mr. Kim was very understanding and helpful. The cleaning staff were very friendly. Overall, I would strongly recommend it to anyone visiting Seoul.
