Wonderful 2-week stay photographing Northern Lights and exploring the middle-north of Iceland. Excellent, comfortable, basic rooms, with a very nice shared kitchen. There's a small store across the street with gas/benzin, a moderate range of foods and supplies, and a selection of fresh fruits/vegetables. Host is responsive and friendly, and multiple times asked if I needed anything.
I can highly recommend Sunnuberg Guesthouse. It is clean, well-maintained, and comfortable as a home base for exploring the region.
