Overally safe and good. but had some difficulty using key (not contactless) Every time I take elevator I need to pull out the key and insert in the slot on the elevator, worst of that one of 3 elevator is broken and another elevator has problem with card slot. All in all the only one is available. However, If the elevator with broken card slot if open, it stop another elevator to come to the floor. It is terrible to go up from the ground to my room.
