We (two persons) stayed four nights at Katrine’s apartment and we enjoyed it very much.
The apartment has a very personal touch which make you feel instantly welcome.
The apartment is just as the pictures promise. People who like to feel like a local will definitely find everything in Katrine's apartment which is located in walking distance to the central train station, close to grocery stores and in walking distance to the city center itself. People who want to explore Oslo will have a good starting point and if the weather is not good, the hyggelig apartment will invite you to read a book with a view on the river.
Due to our arrival and departure times we only had contact with Katerine via text messages but this worked out fine. Throughout our stay Katerine held contact with us, to offer help if we needed so.
We would definitely recommend this apartment and always would return.
