This postoffice is hidden inside Hamburg Central Station, so it can be rather challenging to find…read moreit. But it's always empty, and post office employees are very friendly and happy to help. You can send your letter or package here, or check small but nice selection of stationery. How to find: go inside the central station and look for P&B Press and Books, go inside the P&B and up to the 1st floor. You will see the post stand there.
