It could a great place to stay if it wasn't for the very restricted rules. It's comfortable and perfectly clean, so if you're just looking for a place to sleep and don't mind being always quite, with limited shower and internet hours, go for it. I wouldn't stay there again, but I'm sure it would be a fine accommodation for plenty of people. Regarding the location, it's a 10-min walk to the nearest station with no good cafe or restaurant options very close by. I also recommend checking the time before going to the S-Bahn station, because you could end up waiting for the train for a long time, especially at night.
