"We had a lovely stay at the Karl Johan Hotel. We were only there 2 nights, and had to leave really early the last morning to catch our flight, so only had the opportunity to experience the breakfast one morning.
Pros:
- Centrally located between the castle and Oslo's Central Station.
- You are in the middle of everything going on (and trust me, there was A LOT going on on a sunny Saturday in June!).
- Because you are in the middle of everything, it is very walkable.
- The rooms were really comfortable - Beds, air conditioning, blackout drapes.
- Large selection of foods at the breakfast buffet.
- Love, love, love that every hotel we stayed in in Norway had a card slot when you entered your room to activate the electricity in the room (the only challenge is when you want to charge a device, like a Kindle, when you are out and about).
Cons:
- We were on the second floor and there was A LOT going on in the park across from the hotel. It was quite noisy, primarily the amplified music.
- Walking from Central Station to the hotel only took about 12 minutes, but there were a lot of cobblestones and uneven surfaces to negotiate (we had 3 rolling bags). While it shouldn't be a deterrent to anyone, people should be prepared. We didn't look into a taxi/uber or any other public transportation to get us closer, but I'm sure there are options."
