I stayed in Orange Guesthouse on my own for a 10 days this summer. And I have to say it was one of the best experiences I have had while traveling. The owners were absolutely lovely and comfortable, MR Kim (as me and my friends came to call him) always remembered my name and greeted me and was ready to help with anything. The atmosphere was friendly and relaxed, almost felt like visiting relatives. For some this might not be a good thing,but to me the free spirited home-like feel was spot on. I met amazing people during the stay, the place was cleaned everyday and breakfast (even if really simple) was always ready in the morning. All in all; if you need a comfortabe, free spirited place to stay, that allows you to experinece the lively Hongdae nightlife around it and come and go as you like, well. This is the place.
