Kim and Jen were great hosts. Jen was quick to respond to emails and was very helpful in giving us ideas about things to do in the city once we arrived. Their apartment is beautiful and very well located. Only things worth mentioning is that you have to climb several flights of stairs, which can be difficult with a heavy bag, and that there are 3 bedrooms being rented out with 1 bathroom being shared between the three of them. We didn't have any issues waiting for the bathroom, but it does get noisy in the mornings with people coming in and out of their rooms at different hours. Otherwise, we had a nice stay and highly recommend visiting Oslo, as it's a beautiful city.
