Very small room, but the bed en Wifi was good. You'll get acces to your room with a 6 digit code. So no room keys required. Showers and toilets are in the hallway, so you have to share them with the other guests. You don't get any towels. You can buy small towels from a vending machine for €3,00. For a additional €2,99 you get a simple breakfast with bread and jam, tea/coffee and some orange juice.
The staff was friendly, but spoke almost no english.
10 min walking distance to tram number A, that will take you to Strassbourg within 30 min.
