1 room room of 25 m² in Oslo

I'm travelling out of Norway for few months and want to rent out my room. The room is spacious, cozy in a lovely apartment. The location is great. You get downstairs and the bus stop is in front of you. 50 meters and you are at Grønland T-bane station. The place is surrounded with tons of shops and restaurants. The room is available from 25th of Sep. Could be few days earlier also. I'm willing to rent it out for 2 or 3 months with the possibility to extend. The room is suitable for couples also. Ta
