Thank you very much! We very much enjoyed our stay at Jacob's place. He and his brother were very helpful and nice. The location is very awesome in our opinion for those planning on staying in the Seogwipo area of Jeju.
Jeff was very accommodating! If we visit Korea again, I would definitely stay at Jeff's place again.
Btw, Hongdae area is an awesome trendy area. Jeff's place was truly in better location IMO as it was located in the quieter part of Hongdae, and literally right next to the train station. The busier parts of Hongdae was about 7 or 10 minutes away.
Additionally, we found that there was a citibank bank/ATM nearby. It turned out to be very handy for us.
