I felt myself very comfortable in the apartment like at home. Scandinavian interior, cozy furniture and small details like, for example, handwritten welcome letter, made me feel welcomed. Apartment is located in the best location (very close to the Oslo Central Station, Opera House, etc)
Beside of this, Nina is really nice person who can tell many interesting facts about Oslo and provide practical tips for travelers.
That is definitely the place where I would like to stay again when visiting Oslo next time.
