A GOOD STAY IN BERLIN: Location of the apartment, rooms, beds and price-quality is fine. Quiet rooms, because they are located on the courtyard and not on a main road. Metro stop right outside the door.
Points for improvement: better kitchen equipment (cutlery!), communal entrance (via courtyard) is a bit messy, bathroom curtain was broken, there was a half-dried laundry in the dryer, televisions did not have Netflix while the advertisement suggested this, general instructions for example Wifi, parking nearby, recommendation shops, etc. were missing.
