Ida is terrific and her place is lovely. She told me how to get there step by step via train and tram. It was amazingly easy and she walked with me the 100ish steps to her beautiful and clean apartment.
Lots of great restaurants to walk to. It's also super easy to take tram to central Oslo.
One day I rented an eMTB and rode in the country. It was a quick Uber/Bolt drive to get there.
