Not very clean. They were unable to provide or call for transportation to the airport. Power went out in my room. Not secure doors. Simple lock. No extra door latch for security so if you are travelling alone female be prepared.
The area is close by to Lotte World and can be reached by bus, about 3 bus stops away. There are convenience stores and coffee houses surrounding the property making it very accessible.
The train station is along Line 9, with escalator and elevator on all exits.
