I stayed in this hotel twice on a recent trip through Norway and I was pleasantly surprised. The staff were very helpful, the room very comfortable and the location very central, yet I enjoyed the quietest night I have had in Oslo. I have stayed in several central Oslo hotels, all of which were more expensive than the Europa, yet they were not as good.

Use this hotel during a business trip, very friendly staff. The breakfast in the morning had a great selection. The wireless wasn't the greatest but besides that everything else was great. The washroom is European style, so american's would find it small. The only thing missing was a clock, luckily I had my cell phone to keep track of time. But for the price this is the best hotel in the area to stay at. The hotel was also only a few minute walk to a major T-bane (subway) station which made travel very easy around the city.

Nice hotel in the heart of Oslo, just opposite the Radisson Blu hotel. My room was fresh and newly refurbished, with a very comfortable bed. Bathroom was very small and did not seem to be refurbished lately, but still OK. Breakfast was nothing special, but that does not mean it was bad. Nice price for Oslo, could stay here again!

I had a very pleasant stay at Thon Hotel Europa. The price was a lot lower than the neighbouring hotels, however the "cheapness" did not reflect in the hotel.
Great breakfast, clean rooms, friendly staff, free internet, access to public transport and location walking distance from the city center - what else do you want?
