René's place is excellent! It's located in Tempelhof, which is a nice neighbourhood south of Kreuzberg and has a lot of restaurants and shops. There are not so many bars around there but you can take U6 from Kaiserin Augusta Strasse station to get to Kreuzberg and some other parts of Berlin easily. The apartment is cozy, well equipped and has a moderately fast, stable Wifi. In the basement of the apartment building there are three washers and two dryers. René is very friendly and responds to inquiries quickly. Check-in and checkout were flexible and a breeze. So I would totally recommend his place for exploring cool stuff in Berlin!
