Oslo - Where to Stay?

There are a number of Thon hotels in Oslo. I like Thon Munch, but it is a little father east than Rosenkrantz (also farther away from the harbor). It is in a quiet neighborhood but still very easily connected to the area near the Royal Palace and National Gallery by foot. I have also stayed at the Smart Hotel in the same area of Oslo - but I cannot recommend it. The rooms are "postage stamp" size. Oslo is a wonderful walking city.

The Thon Hotels are also my prefernece: https://www.thonhotels.com/our-hotels/norway/oslo/

Several Thon properties are close to the Oslo S train station with the Astoria being very centrally located and in Thon's "budget" category: https://www.thonhotels.com/our-hotels/norway/oslo/thon-hotel-astoria/
The Astoria's breakfast buffet is good and substantial.

Hi Melinda, we stayed at the Thon Hotel Opera for 3 nights in February. We thought the location was excellent, steps from the train station and a short walking distance to the Opera (we took a tour of the building, highly recommend), Fortress, Peace Museum, Royal Palace, shopping and restaurants.

We recently stayed at the Thon hotel Panorama. Great location and wonderful breakfast buffet.

Ante'ing up with another Thon recommendation here. I stayed at the Thon Opera. Oslo S on one side and the opera house a block away on the other. As with the other locations, a good breakfast buffet. Clean, upscale, nice place.

Thanks for all your recommendations!
