The room is in fact an apartment as It has WC, and specially direct access to the street. TBH I was there for a week and didn't see Andreas as he uses his private part of the house. Room also has a mini-fridge, kettle, and hair dryer. Remember to fly to TXL as the airport is pretty close (in Berlin measures). Also, it's cool downstairs there's a bakery with street terrace, and the WIFI signal from the room is powerful enough ! Overall, more than satisfied and will come again for sure.
