I stayed at Yeon Guest House only for one night, but I had very good time there. Ms. Lee was very kind and friendly, and more importantly, she speaks Japanese very well (I'm a Japanese). Also, this place is very clean and located in a very quiet area. Although the taxi that I took did not take me to this place (I don't know why) and I need to find the way by myself, overall my stay at Yeon Guest House was great, and I will definitely stay here again if I go to the Seoul area.
Our stay for 6 nights in the Twin-room at Yeon Guest House felt exactly like home! Bongok and her husband are very cheerful, friendly and kind. Bongok gave us many tips on where to go in Seoul and answered all our questions! The house is super clean and everything you might need is available. There is a convenient airport shuttle (6005) to and from Incheon Airport; the bus station is on the main street, a 3-min walk from the house. The main street also has easily accessible city buses, a bakery, and a supermarket. It is also a 10 minute walk to Grand Hilton Hotel if you had a convention to attend. Overall, it is a great place to stay in Seoul :) Thank you Bongok for your kindness and hospitality! Hope to see you again one day!
