It was a great experience staying at Felix apartment. It was very spacious, the living room is big as well. Felix let me stay in the whole apartment by myself which is a really nice thing. I was able to cook freely on his kitchen too and I was able to do laundry too. Every time I have a question, Felix replies instantly. I had a good sleep on this apartment. Also, it is just 10 minute walk to the sbahn and 5 minute walk to a very big grocery stores. It is also near to a lot of restos. I will stay here again everytime I am in Berlin
