I'm really glad I've found this apartment! Olaf and Olga were enormously hospitable and helpful. Moreover, they provided guests with precise instructions on how to get to the apartment, which was really important. The apartment itself was a great place for staying, both from aesthetic and practical point of view. Everything needed was included, not to speak about some food products available for guests, which was so nice of host.
I would definitely recommend this apartment for those who wish to spend a couple of days in Oslo and discover city areas and its center with comfort!
