The flat is in a very central location - a short walk from the train station, supermarket and cafes. This also means that it is close to the attractions or the transport links to the attractions. For example it took us 15 mins to walk to the palace and the tram stop to take us to the sculpture park was right on the doorstep. The flat itself is clean and tidy with a well equipped kitchen and it was very helpful that we were given two keys which meant that we could go out separately. Also given that there were other visitors there it was reassuring to have a lock on the door
The only other thing to mention would be that being from a small place we aren't accustomed to the number of homeless and beggers in Oslo.
