We had a 5 day sightseeing trip to Berlin with our 2 teenagers, and this base suited us perfectly. It is a clean and comfortable apartment, vey well located for the U bahn and a range of trams to get out and about. There are lots of good restaurants and bars nearby and it is vey easy to get in and out of town. The flat itself worked well for us although the kids ended up in the larger of the 2 bedrooms as it has 2 beds, even though one was huge. All beds were very comfortable and well furnished. I would certainly recommend this apartment for couples and small groups / families.
