Lena'n' place is perfect for a short stay in Oslo! Really central, close to important tourist attractions, like the Royal Palace and Karl Johans gate. Also close to public transportation and to everything you may need - supermarket, restaurants, stores...
And Lena herself is very nice and took care of everything so we could have a great time at her place.
And three more things: the shower is great, the apartment is really quite and the bed is amazingly comfortable!
Perfect place!
