I am very glad we decided to spend our time in Oslo at Kamil's place. We saw all the positive reviews and had high expectations, which were absolutely met. The house looks exactly like in the pictures, if not better, and is located in a beautiful and central area of the city. The level of cleanliness was probably higher than a hotel, and the overall vibe was very cozy. We really appreciated that every door/cabinet/drawer in the house is clearly marked to show what is inside and whether it is private (since Kamil also lives in the house). These clear boundaries made living there way easier and avoided any awkward situation.
Kamil works a lot during the day, so we had the place all to ourself during afternoon, but we had a very lovely chat in the morning. He is a really nice guy, and you can tell that he is passionate about hosting and learning about his international guests. Bottom line, we wholeheartedly recommend to stay at his place!
