We had a 5 day stay at the appartment from Niclas. He was really transparant and quick with responding. The apartment was clean, and big enough for the 2 of us. The shower was nice and the bed was comfy. We had a nice balcony where we could sit, He left us a couple of beers and water to enjoy as well. The location is great. Unfortunately the U-bahn was under construction so we had to take a bus but still.. all good. It was no problem on the last day to leave out suitcases, Niclas took care of them and we could just text him whenever we wanted to take them. I would really recommend staying here and if we plan another trip to berlin we are definitely going back to Niclas his apartments.
