Great value. Beautiful apartment in a historical building. Everything was spotlessly clean. Conveniently located close to public transit. The communication with Nino was good. All in all, a solid accommodation!
About the thing some others had mentioned about bureaucracy and unwieldy house rules: it's true, but I was not bothered by it too much.
Only a few minor things I was not too fond of: the bedrooms are street-side. If you're sensitive to noises like I am, you might be bothered by / get woke up by the U-bahn rumbles and traffic noises. Lastly, there weren't any pillow options (only quite stiff, thick ones).
