Airbnb looks nice (as on the pictures) BUT for us was an absolute nightmare: the place you are renting has a door, just a single wooden door, separating your airbnb with the place next door (also an airbnb?). You read that right ... basically you are getting free roommates you never asked for included in the price.
We could hear everything they did, they didn't even have to yell. Trying to get some sleep was impossible as they went on until well beyond 2am on a weeknight (and I had to work).
The first night we already had to ask the owner of the airbnb to intervene as the "neighbours" (roommates) were already banging their subwoofer loud well beyond curfew, a few nights later I had to bang on the door at 2am to beg them to stop yelling/partying/whatevering.
Second time I tried to have the owner intervene she said "what more can I do, I'm not the FBI or CIA"
To top things off, upstairs neighbours also seem to be a herd of elephants constantly walking (no clue what these people are doing) across the room with very heavy footsteps.
tldr: check-in was very smooth and friendly but the way the place is set-up right now is just absolutely terrible and not fit for rental. It should clearly be stated in the ad that what you are really renting is big room in a bigger apartment with other people living behind a wooden door that you'll share your time in Berlin with.
I know this is Berlin and you can expect some noise, but I lived in Berlin for 2 years in 4 different apartments, I have never seen/heard/experienced anything like this.
