I heard Hamburg is expensive, but I'm not sure about the suburbs.
How does Altona's cost of living compare to other German cities?
1 Answer
Altona’s cost of living index is 70, meaning it is about 30% lower than the national average. Typical monthly expenses for a single person—rent, food, utilities, and transport—are roughly 30% less than in central Hamburg. This makes Altona an attractive option for those who want to stay close to the city without the high price tag of the core districts.
