The room is clean, well decorated and with all necessary utilities. The host is very helpful as he agreed to let us check in later than 10pm and helped us with the luggages. The location is 1.25h away from Berlin so not ideal, but reasonable given the price. The shower is quite short though so if you are taller than 5’8 you have to crouch to shower. The usual public transport route is to stop at Wannsee then take the 118 bus to Kätchenweg.
