Big apartment with everything you need for a longer stay. Worked very well for our small family. The u bahn is practically right outside, and many trams a few blocks away. There is a grocery store less than 10 mins walk. There are lots of toys and books for a child, which my daughter really enjoyed. When we first arrived a bunch of basics were missing: toilet paper, hand/dish/laundry soap, etc. The host does not live in Berlin so it wasn't possible for her to drop this stuff off, but she made fair arrangements with us. Check-in was also a bit less than ideal because we made it quickly from the airport to the apartment but no one was available until 45 minutes after we arrived. But those were small inconveniences in an overall good stay.
