The apartment is large, comfortable, and very nice. I spent a full month there with my girlfriend while remote-working and it was a perfect home in Berlin. This is probably the most equipped AirBnB apartment I was ever in... especially for families with small children as it even had children's books, board games, and some toys.
The location is excellent... in a quiet residential street in one of Berlin's most beautiful neighbors, with a lot of supermarkets, cafes, restaurants of all kinds, shops, and parks within close walking distance.
The train station is right around the corner, where the "Ring" train lines stop. These can connect you very quickly to other trains (S-Bahn) and subway (U-Bahn) lines, allowing you to reach anywhere in Berlin within a short time. There are also several tram lines passing by nearby.
I'll certainly be more than happy to return to this apartment in future trips.
