Ivar's place would be the best place to live in Oslo. It has it's own privacy within the house and surroundings are very calm. Ivar's place is as it is described perfect equipment for a couple's cooking oven, refrigerator with utensils and resources to make yourself a warm drink. I and my wife visited Ivar's place but we could only book for 2 days as this Airbnb is booked well in advance but we enjoyed here so much. Little far from the city hustle bustle still 5-7 minutes from city centre. The university nearby is worth visiting when we arrived it was Christmas week, university canteen was serving special Christmas meals. Anyone could have meal there. It is to the left of main entrance road from Ivar's home, on B+1 floor. There you could enjoy the best food in best prices. Siri, Ivar's wife, is very helpful and empathetic, she helped us with a balm for my wife's sprained ankle. If you want to book this place be aware to make advance booking.
Thanks Ivar and Siri
