I´m renting out my apartment. It has two bedrooms available for use, with one doublebed in each room. The apartment is only 15 minutes away from Oslo central station with the subway, and the subway is 5 minutes away. You will easily find free parking here, and it is easy to get to the roadway from here. The place is quiet and very cozy, and has free Wifi, television etc.
The subway number 1 and 4 both take you to the stop that´s called "Brattlikollen", and goes every 7 minutes. My apartment is only 5 minutes away from the metro strop.
