The place is almost exactly as described, lovely area, easy acces to public transport!
When sleeping in the smaller bedroom you might indeed need some earplugs for the train sounds, but that wasn't a problem for us. The appartment was warmed up easily despite the freezing temperatures outside : ) The mauerpark is closeby (sunday fleemarket), Al Hamra was a very cute and nice place to eat, and there are plenty of good bakeries as well.
