The U-Bahnhof Schönhauser Allee itself isn't really big, no really fancy architecture style or…read moreanything special. Just a ragelar station you can see in Berlin.
For me, what really interesting are the surrounding. There are lot of shops, supermarkets and restaurants around. It's surely this neighbour does lack of place to shop. Under the station, you can see lot ls of bikes parking here, somehow looks pretty cool and urban. The view on the platform is other thing I like, especially when they turn the lights on.
The station didn't really cover by walls. So at the winter time, it could be really cool. The station doesn't have any info office, but other than that, it got what the station normally needs. If you want to go to the S-Bahnhof Schönhauser Allee, get out of the station first and go behind the mall, then you will find it.
