Bus 54 and 37 from Oslo S: 17 min. Until December, I will have scaffolding outside of my window, and I have no curtains yet. So you may see polish carpenters walk past and hammer on the walls from 07.30 in the morning.
But other than the scaffold, there is a huge field outside, where dogs from far away go to play together. I used to have a dog here (last time: February), so if you are travelling with a dog, that's ok.
