This place was as advertised, but more off the beaten path than I thought at first. It’s a good walk to all public transit options. There were several drawbacks for me and not as many good things, sorry. I think for business travel, it might be okay. If you plan to cook or hang out, not great.
There were zero extra linens, not any extra towels, and no hand towel in the kitchen. So one pillow and duvet with linens, which for one person might be okay, but if you like to sleep with two or more pillows, you’ll do so without linens.
The shower situation is as others have said - terrible design, with water everywhere.
The front door opens directly to the street and has a janky door nob and lock - struggled making it latch and didn’t feel super secure.
The ladder to the bed is steep and also janky…don’t rely on the railing as it shifts and is not secure either.
Good things:
There was an espresso maker with coffee.
It was a quiet, seemingly nice neighborhood.
There’s an Italian restaurant with take away about 500 meters away that was good.
The price was reasonable.
But with all that, I’ll try somewhere else next time I’m in Berlin.
