The place feels like one of those rental housing that were put on airbnb to make a quick buck - doesn't feel like anyone actually lived there. It's apparent from the lack of a trash can anywhere in the house, no hair dryer, no soap, and random food. The pictures also don't exactly match with what the apartment looks like - it's a tad more barren with no dining table.
All things considered, it's clean and in a great location with lots of cool bars/cafes/vintage stores. It's also a short ride from Oslo. I would recommend Ramzzi's place only for a short stay.
