Kjetil welcomed me in the lat when I arrived. He advised me about what to see and what to do in Oslo and I used his help. It was very kind from him to answer to all my questions. The flat is located in a modern building, with a nice view on the city. It is very central so you can walk to the city center (10 mn) or use the public transportation nearby (tram, subway, coaches). The kitchen is well-equipped and the grocery store is very close. Despite the car noises by night, I'll be glad to use this flat again, should I come back to Oslo. I thank Kjetil for his kindness and wish him well.
