My boyfriend and I stayed at Mona's for 1 week. Everything was exactly as described on the listing and Mona was very welcoming and quick to respond to any messages making check in very easy. The studio is in a great location close lots of lovely cafes, restaurants, and shops and within walking distance of the city centre (and their cat and dog are very cute). It really was a prefect base for us to explore oslo from and we would definitely come back if we returned to Oslo.
Thanks Mona and Roy!
