Ilias was very nice and helpful and has given us a very good welcoming, even so we arrived late and he had to wait quite a while on us. his place is exactly the same as on the pictures. big, clean and very beautiful. We recommend his place 100 %. Kreuzberg is a great spot to stay. The neighborhood is central but quiet, almost every hotspot in the district is within walking distance, for tours to the rest of berlin you have direct access to bus (M29) and subay (U1). We would wholeheartedly recommend any traveller to find a temporary home in Ilias apartment.
