Great apartment, perfect for larger groups (we were 2 families, 4 adults and 6 kids) and it suited us perfectly. Very clean and modern. We asked for an additional bed sheet and a hoover and got it provided within hours in our apartment while we were outside enjoying Berlin. All this and the rest of the communication happened on-line via Airbnb or the dedicated website of Ben&Simon without stress.
Location is also very convenient with the Wedding station giving access to U and S Bahn just close by. A modern supermarket and a gas station makes it easy to get anything you need for short stay as we had.
I clearly recommend this apartment and Ben&Simon as manager of the place. Will definitely book here again next time we come to Berlin.
