Stefan is a great host. We were in touch via airbnb to arrange my arrival, and he was so open to my schedule. When I arrived we talk a little about me and he gave me tips about the city and how to reach it. Every time he saw me, he asked me if I wanted something to drink and asked me how was my day in Berlin. One night he and a friend invited me to have dinner with them, unfortunately I had to refuse it because I had already eaten. The room it is exactly as the picture. It is located 45 min walking to Brandenburg Tor, I did id walking, but there are a lot means of transportation from his house. Also, really close there is a big supermarket, and you can cook in his house. If I have to go to Berlin, I will definitely go to Stefan's house again.
