Great location with plenty of shops and restaurants nearby. Tram stop is on the doorstep and gets you to Alexanderplatz in no time. The place itself was very spacious and had everything we needed for cooking/cleaning/eating etc. We were also impressed with the efforts to create a sustainable household. Logging into the wifi each day was a minor inconvenience but it worked fine once we were connected.
Everything was very clear and well organised so we didn't need anything from Claudia but she let us know she was around for anything we might have needed.
We would certainly stay here again.
