Here is "Amika Tattoo", website is https://amikatattoo.de/

Here a gate is missing. The footpath inside the 55 building (here incorrectly mapped as a road) is not open to the public.

Für Wein & Gut. Die Besitzerin sagt, dass die Öffnungszeiten auch etwas vom Wetter abhängen. Bei gutem Wetter wird auf Nachfrage von Kunden auch früher oder länger geöffnet.

Here is a campus of "iu international university" - https://www.iu.de/campus/berlin/

In between the barbershop and Haroun, there is another shop "Sushi Mana" (not mania!), it's a sushi shop. The website is https://www.sushimana.de/

Both "Technik Phone" and "Hairstyle Paris" are mis-located. There are both one building further up, Technik phone is to the west of the 53 gate, and Paris is to the east of the 53 gate, in the 55 building. So both need to move west from their currently mapped locations.

There is a gym here, "FitnessFirst Women".

There is a netto here, not a hotel. The hotel is in between DM and EuroBistro.

The women's gym is on the other side of the netto supermarket. Well, it's on top of the supermarket, but the entrance is there, not here.
