Seeking two bedroom apartment in Oslo!

Hei! I have just moved to Oslo from London with my 7 month old son and a very mellow ginger cat. I have been transferred here with my job as an energy analyst — I manage a team of environmental markets analysts that is based here, so my job is pretty stable. We are here for at least the next three years, but perhaps longer and have Norwegian ID numbers and everything, although I am still playing ping pong with the banks over account paperwork, but BankID is coming! I can provide proof of employment and previous rental references in London. I am keen to get settled so that I can get the baby on a waiting list for kindergarten, and also to have access to more of my wardrobe than what I brought in my suitcase. We are open on location — Oslo is just so lovely — but I would prefer something with a balcony and light, and want to be at least on the third floor or above with a lift. Thank you very much for your consideration!
