Big O show Guesthouse is located close to the trainstation Yeosu-Expo. They let me check in early and I got a 4 bed dorm but I booked a 8 bed dorm - was great!
What I liked the most about this guesthouse was the breakfast. From 8-9:30 there are toast, jam, eggs, salad and sauce. I just took a toast but a few minutes later one of the hosts made me a perfect omelette with salad and served it to me. It continued and the lady made me milkshakes without any request or asking me, she just served it. That was so awesome. Hostel was not booked out so I stayed in the 4 bed room alone.
When I wanted to go to the bus terminal they even drove me to the terminal. Would have loved to stay longer but I was limited in time. Totally recommended
