Martin's place is absolutely fantastic. It's a uniquely structured underground apartment with the perfect mix of British charm and Kreuzberg grit. The apartment was extremely spacious and the rooms were comfortable and meticulously presented. This is the perfect space for a long or short-term stay. Martin was an excellent and welcoming host. He was very communicative and made sure that any questions we had about check-in or the local area were answered in a timely manner. Absolutely would recommend to everyone and am looking forward to hopefully booking again in the future! Five stars!
