I went to Berlin to the ILA Berlin Air Show last week and I stayed with Hannes for four nights. He is very nice and he picked me up when I arrived to the Sbahn Station. I bought my food in the supermarket that is 3 min walking away and I cooked like at home. The house is nice, clean, and quiet, the neighborhood is very cozy; I had to come back late at night, but I still felt safe. The S-bahn is 8-10 min walking distance and you also have the option to use the bus depending on where you want to go. The first night I had dinner with Hannes and we had a very nice chat while we ate, I really enjoyed my time staying there and the most important thing I would definitely go back, I highly recommend Hannes as host!
