I stayed at Suzanne's place for 3 nights which is central to a lot of local attractions. After a bit of troubles with check in, I was welcomed by a beautiful cat which definitely owns the place and the room. So if you are allergic or don't like cats, then it might not be the place for you.
The bathroom needs a better lighting and maybe some cleaning. The same goes for the kitchen and fridge.
Overall an OK experience given the high season in Berlin now.
