Good budget option on the edge of Schöneberg distract. The room was clean and had obviously been decorated and accessorised with care. Steep ladder-like steps to the attic bed may put some people off but it was OK for us. The door to the room is a simple sliding thing with a padlock, so if you're particularly security or privacy sensitive that might be an issue. Again, for us it wasn't really an issue.
My German is rusty but I just about got by. I think I'd recommend that you're a competent speaker of the language for staying here.
All in all, this did the job and was all pretty straightforward.
Thanks Annegret!
