We had a two week stay at Marls' apartment and we really liked it.
The location is very good, with the U-Bahn station just in front of the door and good Bakeries, Cafés and Restaurants are close by. A big supermarket (EDEKA City) is very close too, which is super practical.
In the place's description you'll find "Free street parking", but this is outdated and no longer the case. Marls tells you about options in advance though. If you have an EV, you can charge it in front of the building (parking for free, up to 4 hours).
Not listed under amenities is a TV, which was a nice surprise. It doesn't have cable, but we didn't needed it, an HDMI cable is available for using with your laptop or such.
WiFi is not super stable, but good enough.
The apartment was very clean and we have nothing to complain. Don't be fooled by the reviews that mention the mattress, it's totally fine. We can really recommend Marl's place!
