It’s basically a hotel. The room has a nice kitchen with oven, fridge and microwave- however you will have to buy things like salt and oil by yourself- which compared to private apartments is rarely the case. You’ll also have to buy shampoo and soap and all necessities.
Otherwise a good location, right next to public transport.
If your check in is on the weekend you will have to check in by yourself, and the instructions were not crystal clear for that.
You’ll also have to pay the city tax, which is nowhere mentioned before you book the place, but that’s the case for all Berlin AirBnBs (it was my first time in Berlin and I wasn’t aware od this).
Overall I’d say it’s good value for a stay longer than a week.
