We were met on our arrival by Alan who ensured that we were aware of how everything worked in the apartment. Alan spent time showing us maps and suggesting wonderful locations to eat and visit during our stay. Alan and Kasia had put together a wonderful pdf of places to go and see and how to get there. Nothing was too much trouble. Alan gave my husband a bottle of wine for his birthday which was very thoughtful. The apartment was very central, close to public transport and in a quiet residential area and as described. The apartment was very comfortable and we enjoyed our stay and would return if we are in Berlin again. During our stay the weather was quite cold but the apartment was very cosy.
