Good clean biggish rooms, with TV, safe, radio, aircon, small kitchen, desks, pull-out table and 2 chairs. lots of storage space. Laundry and gym onsite (not tested). Helpful staff, great location near Gwangjang and Dongdaemun markets. Reasonable basic breakfast $9 extra. Hint1. Take the airport limo bus, faster and quicker and far less tiring than the subway (trust me, i carried 2 suitcases up too many stairs). Hint2 byo coffee and tea, especially if you like black tea.
In all, would happily recommend this hotel!
