Very nice apartment with an amazing view and a balcony, located in a central part of Oslo.
Just next to Akerselva (the river), Ilaparken (the beautiful park), and walking distance to Grûnerløkka, Alexander Kiellands plass, Sagene, Torshov, St. Hanshaugen. 10 mins ride with a bus from Oslo S, and good bus connections to almost all parts of the city.
The apartment has a good standard, a good atmosphere, and probably all you need for your stay.
Bus 54, 34 and 20 is very close, also close to many trams.
