Stayed 4 nights, switched rooms after 2 nights because the first room was too small for 2 people. Friendly hot"else staff, even had complementary umbrellas for us to use. Hotel is in a good location, but it is a bit difficult to find, because it is located in a back alley, and cannot be seen from the main streets. However, they have cards for the taxi drivers and it worked fine for us.
Hotel has great access to Insadong shopping areas, subway and Seoul station. Lots of restaurants and coffee shops nearby as well.
The rooms are creative, although a bit small. For a single traveler, it would be comfortable. Rooms could use some more functional features, like hooks for towels, shelves to place toiletries and personal items.
I enjoyed my stay, and would stay again.
