The apartment is just great like the Moabit district as well. There are nice view from the balcony and furthermore the building despite beeing quite old has an added elevator which is convenient when the apartment is on the top floor. The apartment itself is not that old but almost new attic apartment. The staircase room is decorated with really nice street art type of paintings and has some memories of the buildings history as well. So use only elevator when going up otherwise you'll miss them. You find everything you need already on Birkenstrasse or close by like groceries, nice small shops and restaurants and even a car tire repair which I actually needed. And the public transportation is literally close when the Birkenstrasse metro station is just couple of meters from the door in the case you would like to see something else in Berlin ;)
