Marianne and her family were fantastic hosts, very welcoming, and with a lot of wonderful suggestions on what to visit and where to eat.
The room was nice and spacious, as was the apartment in general, and is situated well within walking distance of the city centre. Especially convenient was the bus stop to/from the airport, which is only 50 meters away.
This was our first time in Oslo, and I don't think we could have found better hosts. Do not pass this listing up!
Thanks again Marianne, Fredrik, and Agnes for hosting us and making our trip so memorable!
