Some confusion on directions getting to the flat started our stay off on the wrong foot. Follow google maps-S9 does not go all the way to the flat.
A good space - well equipped kitchen - great location - great shower and hot water and water pressure. Good heat throughout apartment. Good washer
Not so good things - sporadic and slowish wifi. Uncomfortable bed and very uncomfortable pillows.
Positives- close to public transportation station and two grocery stores and many bars and restaurants.
Overall, a good home base for exploring Berlin.
