Øystein and Kari were lovely hosts! They responded quickly and were proactive. We arrived later at night and they were flexible with key pick up, which was appreciated. The fire alarm also went off while cooking and Øystein immediately came down and helped us fix the issue.
One issue we had was with cleanliness. This does not seem to be listed in other reviews, so it may not generally be an issue, but we found left over food on some of the dishes put away and there was dust on some of the ovenware and appliances. We also found that the toilet had a bit of an odor, as did the towels. The only frying pan was old so it burned food easily and was difficult to clean. There is also a small child living directly overhead, which was loud at times.
That said, most are fixable issues. It was very reasonably priced, in a decent location, and had all listed amenities, so it is a good option for those traveling on a budget. The hosts also left a typed guide for Oslo, which was a nice touch!
