Had a great experience here.
Despite breaking my collar bone 2 hours after arriving at the hotel (went Tobogganing at Kanthaugan!), the hotel was very helpful. They looked after taxis, rebooked car hire, and generally gave great advise.
They had 3 large school parites stating in the apartments on site, but because of the way they organised breakfasts, you would not have noticed. The De Luxe family rooms were big, warm, and had a great location. They cost NOK1195 per night, incl. breakfast.
We borrowed differents pairs of ski skates, and sleds/togoggans for free from reception, which meant we had enjoyment right at our door step.
It was really great, and despite my own misfortune, I would love to return some day once I recover.

A few words of advice:
Don't follow the signs for Birkenbeineren ski station as we did. There are a lot of signs for these around the town, but this is way up in the mountains, which were heavily covered in snow. The word ski station is not on most of the signs, it's just a symbol.

The tickets for the Hunderfossen Vinterpark are discounted at the hotel reception. Adults = NOK137 and Children = NOK102 v's NOK 195 and NOK 145 at the park itself. We saved over NOK200 by buying them this way, and did not have to queue when we arrived at the winterpark.

A basic hotel located a short way out of town. Another place where they lost our reservation (the motel part has bunk beds). We stayed in the hotel section for three nights. Our room (307) was quite large but fairly basic as was the bathroom. There were no amenities in the bathroom. The hot water service was a bit steady as well. The TV was located on the far side of the room and was tiny so it was hard to watch it. The view was limited to the carpark and the woods beyond.
The breakfast room reminded us of an old fashioned school room. The spread on offer was okay but what really got to us was the signs on the tables asking us to pack up our plates when we had finished with them and put them on a trolley to aid the kitchen staff. We thought we were here on holidays...

Nice hotel a short and quaint 10 minute walk from the centre of town. The rooms are basic, but clean and functional. No bathtub, just a shower that is open on the floor, so water splashes all about. The breakfast is good, but basic. The hotel sauna was very nice after a day of cross country skiing, but it's split with a separate sauna for men and women - clean, but again basic.

The area has exceptional cross country trails (about a 20 minute car drive away) and unlike many other countries/areas you basically drive to a trail, park your car and off you go, without any boundries. The cross country trails are really quite exceptional.

In town there are several good restaurants and shops. The drive to the hotel from Oslo's main airport is very easy and takes about 2 hours.

Had a lovely break here in Dec 02. Simple inexpensive apartment, clean, nice small kitchen, dishwasher etc.

About 15-20 minutes walk from train station. 25 minute bus to Ski area.

Nice walk to the local quiet bar in the evening.

If you don't mind the walk/ taxi from the train station (i didn't), its perfect!
