I had a great time in Berlin staying in Georg's apartment. I didn't get to meet him in person, but he responded to my questions with promptly with detailed email responses. My grandma would have chaffed a bit at the housekeeping in the common spaces, but I didn't mind, and the room itself was clean and comfortable. His roommates were welcoming and helpful as well throughout the visit, and I enjoyed getting to talk with them. I wish my own apartment had a great location like theirs does, its close to both a shopping center and a U-bahn station. There was also a pre-WWI swimming pool that was within walking distance that I enjoyed visiting. Overall a great first experience staying in Berlin.
