I was only in Oslo for 1 night, but I wish I had a longer time there. Mona's apartment is very cosy, located in a convenient and quiet neighborhood. The room (and the apartment in general) makes you feel very welcome, it almost feels like home. It was always adequately heated, especially since it is winter. The heated washroom floor is a very nice touch as well. Location wise, it takes about 15-20 minutes to walk into the central town areas, and about 5 minutes if you want to get to the waterfront to take a walk along the coast. Mona is a very hospitable host who makes sure that you feel welcome. She was very accommodating and extremely helpful in giving tips on where to explore in her beautiful city. Her sincerity in hosting is very heartwarming. Wonderful and beautiful place to stay while you are in Oslo!
