Andre and Pedro are so nice and helpful. When we back from Tromso, we stayed another 3 nights in Andre 's place, the apartment is cozy, close to airport bus station (5-10mins walking), surrounded by several supermarkets. To Oslo central, within 30mins by walking. We enjoyed our stay in Andre 's place, we had good chatting with Andre and Pedro. Highly recommend!
Wish you all of the best! :)
