The apartment is located in a VERY good area and accessible by any means of transport (S-Bahn, Tram, Buses). The Brandenburg Gate/Reichstag are about 2.5 km away and can be reached by foot.
The only notes were the shower sink and sofa bed linen, but these were the minor ones and have been mentioned to the host in PM and I think will be fixed.
Thanks a lot!
PS. Keep in mind that you need to have your own soap, shower gel and shampoo! We had to buy it all once we figured out there is no available.
