Unfortunately, we didn't have a great experience. In fact, we ended up not getting to stay there. We rang the doorbell probably 15-20 times over 10 minutes during the timeframe we discussed arriving, all with no response. Unfortunately, this was at 10:00 pm, and we didn't have too much time to wait. Not having any means of communication other than wifi, we drove around for about 20-30 minutes to find a McDonalds. Once in there, I messaged Amad but I didn't have too much time to wait for a response. After waiting as long as I could, I booked a hotel outside the city. When I closed out the webpage, I got Amad's response, and he was apologetic and more than willing to accommodate us. I really wish we could have stayed there. The location was great, and we felt safe. Metro transit in Berlin was very good, and fast.
