Unfortunately I only had two days in Oslo, but thanks to Mona and her perfectsuggestion on how to explore Oslo on foot I did manage to make the most of it. She has been a wonderful host. The house is lovely and cosy and I actually felt at home. The apartment is very close to the city centre and located in a great area. It's a very short walk from the centre and has a really good transport connection.
It was my first experience with AirBnB and I loved it.
Thanks.
