Great hosts and quick to communicate with us. The apartment is very clean, towels are lovely and soft and nice balcony. It is up 3 flights of stairs. It's very spacious with coffee maker (bring your own filter and beans), kettle, fridge, stove and small freezer (no microwave). It's a 10 min walk from a large residential shopping mall, and a few U and S bahns, it is a good 30-0 mins from Alexanderplatz but we were happy to take it easy and did not spend too much time in berlin city itself. The neigbourhood is quiet, not much around it.
