Weakness: WIFI Nework is too slow. Download and play mobile games takes long time for loading. The problem lasting for one week. 4 star Hotel staff English oral proficiency should be improved as well. Buffet reception staffs forgot our booking and could not explain to us properly & timely. We are really disappointed to the services. Strenths: Clean environment. Nice city views. Although we are not assigned to skytree view room. The ordinary street views are great.
