The location is fantastic! There is a FamilyMart right below, and shinkong mitsukoshi is just beside the building.
Fyi, Kim mentioned that we should exit from K12 but the nearest exit is actually Z2. K12 isn’t so far from the place, but if you have many luggages or if it is raining, then Z2 is definitely a better exit.
Tips - there is a elevator between Z2 & Z4 for your luggages.
