Where should I setup a bank account in Oslo?

"Before retiring in Oslo, expats should be aware of the cost of living, which is higher than in many other countries. They should also be aware of the language barrier, as Norwegian is the official language of the country. Additionally, expats should research the healthcare system and the availability of medical services in the area. It is also important to research the tax system and any applicable tax breaks for retirees. Finally, expats should familiarize themselves with the culture and customs of Norway to ensure a smooth transition into their new home," remarked another expat in Oslo, Norway.
