Franks apartment was very clean and comfortable.He put many facilities for guests in his room. He was so thoughtful. I felt like being at home and had a great time in Berlin. Location was also good , only 5minutes walking from the tram station.Near the apartment, there were nice restaurants and cafes. I went to some restaurants and cafes which Frank recommended. They were so pretty and good taste! When I come back to Berlin,I would like to stay at Franks apartment again.
