Security is excellent! There are two doors at the ground floor which need card touched to be open. And the elevator also needs the card to be operated. Finally the door of your own room needs the card.
All the things in the room is clean and new.
Something I’m not very satisfied with may be: the window can’t open so the air in the room is not very fresh. And there are no stove and pot in the kitchen, you can only use the microwave and toaster to cook.
