Amiga Inn Seoul offers its guests multilingual staff, tour/ticket assistance, and laundry facilities. Public spaces have free WiFi. Amiga Inn Seoul also features an elevator, a microwave in a common area, and a water dispenser.
Smoking is allowed in designated areas at this Seoul hotel.
The staff (which should be a family) are nice. It requires around 5-10 minutes walk from subway but I think it is still safe at night for single person because there are some restaurants nearby which opens up to late night. The room overall is clean but it is a bit old, with yellow spots on the wall and the TV monitor is broken. The wifi connection in my room is none actually. Therefore, I would recommend if you need a short stay in seoul.
