We stayed at Alan's place while we were in Berlin for 2 nights. It was great! It definitely isn't in the middle of the tourist spots BUT it was perfect for us. His apartment was cute and clean, and we had plenty of space. The neighborhood is super cute and we rented bikes right by the house and biked all over the city! This was one of our favorite things about Berlin. Alan wasn't available to meet us for checkin but he let us know before we got there and his friend was there waiting for us. I highly recommend Alan's apartment!
