Maison d'hĂŽtes dans le centre-ville en liaison directe avec un centre commercial, Ă une courte marche de Centre commercial Lotte Outlets Seoul Station
It's not flashy, but it's fine and very cheap. Paid ÂŁ33 the night before my one-night stay. The room was OK, but they oddly have a basket of small hand towels, and they don't provide bath towels. Also they have a basket of "free earplugs" on their reception counter which is concerning when you see it but it's because construction around there. There is a communal kitchen in the basement, meant to have free juice and tea but there was nothing when I was there. WiFi is fine.
Basically, if you need somewhere quick and cheap to stay near to Seoul Station (which is where the rail to/from Incheon Airport goes), this is fine.
Do finally note though, it's on a short but surprisingly steep hill.
Located near the main train station this is a no frills hotel that has a washer and dryer. Rooms are smaller, there is no front desk from 5-10 am. Good for a few nights they did have several business travelers
