I stayed at Heidi's apartment while I spent a few days in Oslo. It was really clean and tidy, modern, and had a great view. It's in a really nice part of Oslo and was well-located to explore the city by foot. Heidi sent over a really comprehensive set of instructions for getting into and using everything in the apartment as well as lots of local recommendations of places to eat and shop which was really appreciated! There were only a couple of negatives: the bed is two single mattresses which I found a bit uncomfortable as there was a noticeable gap between the two mattresses; and I found it a little strange to expect us to take the bins out at the end of their stay - that's always been something I've considered to be a part of the service/cleaning fee. I also found there was a bit of a lack of lighting during quite dark winter days in Oslo. Overall though, I'd really recommend staying here.
