The airbnb was clean and functional, located in a safe building in an area with lots of restaurants and second hand shopping. It was also super close to the underground public transport which was great for getting around Berlin. Arno was a very helpful and responsive host. The only thing to be aware of is the sleeping situation as you have to climb a steep ladder to get to either bed. For us, that was not a huge problem but could be potentially unsafe. Overall, would recommend!
