We found this hotel a bit depressing. We were booked into a 'superior' room, but the carpet was old and stained and the furniture was tired. The room had flourescent lighting. When it rained it made a lot of noise on the tin windowsill. Breakfast felt a bit sparse and penny-pinching - there was a limited choice compared to the other hotels we stayed in in Sweden. However, the staff on the front desk were friendly and helpful. After one night we moved to the Best Western on Strandgatan which was more expensive but worth the additional money and right in the centre of town compared to the Kung Gosta which was a 15 minute walk.

We stayed here for two nights. The room is nice and clean. One kingsize bed and one "bunk-bed" (sleeps two).
The bed was comfy and there were extra pillows for us in the wardrobe.
Breakfast was good, with lots to choose from. Fresh baked bread. Dinner buffet was ok. There is a small pool indoors and a gym.
The restaurant is ok, a bit dull in decor but with good prices.
Location is not the best but you can easly walk into Mora town in a few minutes.
Staff was friendly and alert.
Overall a good stay.
