This was an excellent place to stay. I received a very friendly welcome from Koy and Svein on arrival, with many tips for exploring the local area and travelling to and from Oslo city centre. The check in instructions included some useful information on how to use public transport to get to the house (I used bus number 74, which stops nearby. I also used the metro early in the morning when I was leaving, which is slightly further away. The house is about four miles from the city centre but very easy to get to.). There is a code for entering the back door, which worked every time I used it without issue.
The room which I stayed in is very accurately represented in the listing photographs, and is right next door to the guest bathroom, which is large and clean. I was offered the use of the kitchen, which given my brief stay I didn't take up but it looked exactly like it does in the listing. The house is in a quiet area, nowhere near any busy roads, so I didn't hear any noise during my stay. Overall, I would recommend staying here to anyone. You need to climb a few steps to the entrance, but once inside there are none, unless you need to use the upstairs toilet (if the downstairs bathroom was occupied for example).
