Overall everything was really nice! You basically have everything you need, breakfast was great, we also tried the hotell restaurant, food there was good as well, only reason why i gave 4 stars and not 5, is that the floor of the room was sticky and the toilet seat was a bit hard to sit on, but other than that, this was a great hotell to stay at!
We stayed here for a single night on our way from Stockholm to Oslo. It is a good stopping point in between these cities and Karlstad itself is a pretty town, but small. The hotel room was clean and reasonable with good wifi and a good shower. There is a small bar in the hotel with friendly staff, making that a nice place to have a relaxing drink before dinner. We also had dinner at the hotel and while it was nothing special and served as a buffet, the food was wholesome and reasonably good. The included breakfast was a bit spare, but perhaps this reflected the fact that we were shooting for a very early start when we left.
