Hello there, Hallo :),
Welcome in Rotherbaum, one of the nicest areas in Hamburg and also part of the center of HH.
You will stay in an old charming building right next to the Alster / Hamburg University and Dammtor Station which is quite a central position in the city.
Coffee shop (Mandelmehl & Zuckerei -> they have wonderful french baking) is 10m away / Cinema and supermarkets are 250m away as well as great restaurants (Italian, German kitchen etc.) for all the budgets.
