My first impression is a beautiful cosy look of the house. Traditional and modern combined together. Then I met the hosts who are extremely nice. They helped me in everything. Not only they showed the good places for me to go but they went together with me and had dinner with me. The room facilities are all good. Strong wifi. Warm and clean toilet. Specially very good soap and shampoo which are rare to see in any big hotel. Another impressive thing is breakfast, one of most delicious and well-prepared meal I ever had. The location is close to nearby attractions. It just takes minutes to walk to Gyeongbok-kung, the Blue house or traditional village. The mountain hiking site is also nearby. There are local market nearby where you can get different traditional food with good price. There are also many western style restaurants around.
This would be my most recommended place for staying and exploring Seoul.
