It’s a small but absolutely lovely apartment right across the Alster lake (Schwanenwik). 2 min walk to a bus station which takes you to the main station in 5 minutes (two stops) and 5 min walk to the subway (U3) which takes you to the main station in 5 mins also. Walking would get you there in 15 minutes.
It has a beautiful view into the green garden and it’s also pretty quite here, perfect space to relax in the middle of a big and beautiful city. :)
