very good located apartment to explore all parts of oslo! next to a kiwi supermarket (the not-so expensive kind) open from 7 to 11!
clean room, spacious (more space then expected on photo), good working wi-fi, clean kitchen, close to central station, walking distance of nice restaurants and bars.
We stayed in the summer and in the weekend (friday saturday night) there is a lot of noise on the street (a lot of people talking, walking by, cars and trams passing by) but on sundaynights it was quiet, so it was probably the combo weekend-good weather. I expect that in winter you are not at all disturbed by streetnoise.
