Nice apartment filled with daylight, in the nicest part of Oslo. A young host who knows the citys secrets and that shares all the tips! Dine at one of many good restaurants, or buy fresh products from the fantastic markets and make it at home.
I allow visitors to bring visitors home for dinner(for example), as long as one lets another know. Clean up after using kitchen, and when normally appropriate. No smoking inside. And we take our shoes off inside in Norway.
