I spent a week in this lovely cottage. The cottage is located immediately behind the owner's house. The house is a corner lot and during the day there could be noise from cars passing by, but everything was quiet at night.
There is a bus that stops literally at the end of the driveway or you can walk up the hill about 7 minutes (I'm a slow walker) to the metro #1. I usually took the bus into Oslo in the morning and returned using the metro. There is a grocery store located right by the metro stop and then it was a downhill walk back to the cottage.
The bed is very comfortable.
