Sebastian is a fantastic host! He was very quick to respond to any queries we had throughout our stay. The flat is as described and was comfortable for my husband and I and our two children. The beds were super comfortable.
We became daily locals at the Göttlich cafe around the corner (great coffee & croissants!) and with two young kids we were grateful to have the closest metro stop (Amrumer Straße) just a few minutes walk away! It only take about 20mins max. to get into town on the train which made it easy to sightsee in central Berlin. There is no washing machine in the unit but there is a laundromat 5mins down the road.
Overall we had a great stay and would definitely recommend Sebastian and his great apartment! Thanks for a great stay!
