Very nice stay in Grethe's cottage.
Location is a big plus since it is very close to Skøyen train, tram bus station (same zone as Oslo Central). There is a convenient supermarket just next door.
The cottage was sparkling clean. Hosts were responsive to any need or request which is much appreciated.
Checkin/out is very easy at anytime.
Cottage has very limited kitchen equipments. These are very basic and must be considered if you plan cooking at home.
Cottage is next to train tracks. I'm used to city noises, and it was not a problem to me. However, it might bother some other travelers.
