Absolutely fantastic stay and location; very safe and well-appointed location in a secure residential building, SMACK in downtown Oslo.
LOCATION: For tourist or business visitors, it really doesn't get any better than this. The apartment is on the fourth floor of a large hi-rise building that occupies a full city block. The bottom floor are shops, restaurants, etc. ... the higher floors are apartments. There is a magnetic key required just to access any residence door; there should be no security concerns. The building itself is located only a couple of blocks from Oslo S train station, Karls Johan Gate (the main street for everything touristy in Oslo), and from the downtown Oslo waterfront (Opera House and the the path to the boardwalk). Coffee, quick food, restaurants, 7/11, grocery store, and bars are all within QUICK walking distance. However, I mentioned that this was "secluded" as well... the reason is, this building is a couple of blocks away from the main bar/shop streets, which helps limit through traffic and keep it quiet. While it is on main roads (there is a tram stop right outside the building), you don't have to worry about a lot of nearby traffic. Lars' apartment is on the inside of the building, which also helps with quiet.
PLACE: Great, fully furnished apartment. This is well suited for a single person or a couple. The bedroom is secluded, but with an open doorway to the main area (which makes it studio-esque). It has a full kitchen, a TV room/den with a couch, and an outside porch/balcony.
For anyone that has read any other review by me, bathrooms get their separate review. I will happily attest that Lars place has a very clean and up to date bathroom. A nice part of being in the building was that there was an abundance of hot water, even during 30 deg days and nights (in recent trips to Barcelona and Prague, I unfortunately could exhaust the hot water before concluding a long shower).
