Stefan and family are great hosts, they were very accommodating and made me feel right at home. I waslate for my check in by 6 hours, Stefan stayed up until I came home and gave me a walkthrough at 1 AM in the morning (Thanks for going above and beyond Stefan).
I would have liked to stay for more days here, unfortunately they were fully booked.
Lovely home, lively family and Stefan is a treasure trove of information about all things Berlin.
As far as transportation is concerned, you need not worry. There is a bus station one minute from here, it will connect you to Rathouse Spandau (U + S) network in just 10 minutes.
Hope to stay here again!
