This place is a budget friendly stay in Berlin. Stayed 2 nights and it worked good for our needs which was a place to sleep and shower. Communication with the host was easy.
One thing to note is that there are other airbnbs attached to the building and all the keys are for those units are accessed on lockboxes which are mounted directly to the front door frame. So at times, when other people are retreiving or dropping off keys, you might think someone is trying to break into the place.
Also, when we arrived, the place smelled like smoke and we found a sock on the floor in plain sight which made us question if the place had been cleaned or not.
Like I said, it's a budget stay.
