I really enjoyed staying at Ole's apartment. I stayed with my 8 month old baby and the hosts provided all the baby gadgets we needed, including toys! The apartment is in a lovely area with the pretty walk by the river, it has a supermarket close by and an easy access to public transport.
The covid testing clinic was 2mins away which was also very convenient for flying back!
I would highly recommend it and would be happy to stay there again on my next trip to Oslo.
