We booked for 5 nights but stayed only one. There were numerous issues but the most major was the bed and pillows. We have been avid travellers for decades. We have never slept on a more uncomfortable mattress or pillows. I developed a migraine due to neck and upper back pain from the bedding. The fridge contained leftover food and remnants of a cleaning rag. My partner had to re- fix the toilet seat (I kid you not!). There was no internet because the host was reluctant to recharge until the new month started a few days later. We were warned not to stand on timber decking as it was rotting. One glass door was not working. Part of the external blinds were not working, reducing our privacy. Finally, Kreuzberg is a LONG way from the centre of Berlin and major tourist sights. It has a very run down seedy feel about it. You can stay in a nice hotel in central Berlin for almost the same price. I have made a claim for compensation to the host. He was completely negative and rude. It is currently being dealt with by AIrbnb.
