Zainab's place is truly remarkable! It is clean, nicely furnished, and close to public transportation. To me, it may be the perfect place for a single traveler. It has everything that you need, and the flat is newly built. So, there aren't any unpleasant surprises. Getting to the city center is pretty easy. There are buses and a metro. If I revisit Oslo, for sure, I want to stay at Zainab's place.
