Where should I setup a bank account in Karlsruhe?

"Before retiring in Karlsruhe, expats should be aware of the cost of living, which is slightly higher than the national average. Expats should also be aware of the language barrier, as German is the official language of the city. Additionally, expats should research the healthcare system in Karlsruhe, as well as the availability of public transportation. It is also important to research the local culture and customs, as well as the job market, to ensure that the city is a good fit for retirement," mentioned another expat when asked about moving to Karlsruhe, Germany.
