Large apartment, located well for transport. Needs another sofa in living room to be comfortable, as people end up sitting at dining table.
Shower floods everytime you use it as the shower shield is not sealed and is very small
We found the area OK to explore rest of the city, but other than the Kitkat Club which is open til at least 7am and you can hear faintly, no local bars to visit (esp if you are in Berlin Sunday-Weds as lots of places close in the week!
Finally, we had a a problem with fruit fly, which multiplied whilst we were there despite having no fruit in the apt, and only eating breakfast there.
I think there may be nicer areas to stay.
