Gamlevaerket is three things in one. Mostly, it's a restaurant with a bakery and patio. But they have guest rooms, priced well and just about the best location you can get if you are in Sandnes - on the main shopping street, near the transit center / train station, and walking distance to everything Sandnes has to offer.
One tip if you stay at Gamle Vaerket - get a room that has a window to the "outside" - ie: real nighttime air. We didn't have A/C in our room and it was one of the rooms with a window opening to the inside of the hotel. Those windows can let in hotel/bar noise, but they don't cool the room down much. We still liked our room, and they had fans which helped keep it somewhat cool.
(Note - their web site lists air conditioning as a feature - either #201's A/C was busted or they are generous with their definition. The outside hallway was cool, so somewhere there was air conditioning, but our room tended towards stuffy and we didn't see an obvious way to cool the room other than the two fans. I'd book one of the outside facing rooms just to be sure.)
Breakfast and wifi was included. The breakfast buffet was good, including a fair variety of basics with a few regional flavors for the locals or the adventurous (herring and brown cheese, for example).
