We stayed a week in Rune’s apartment. It is very large and comfortable with a lovely balcony with views over rooftops and the sky. It is in a fabulous location with lots of shops and restaurants, a really good grocery store and good public transport nearby. Also an easy walk to downtown and the waterfront in one direction and Frogner Park in the other. Check in was easy and we had good communication with Rune. It is a 4th floor walk-up but we managed just fine. I recommend staying at Rune’s when in Oslo and would stay there again.
