We can absolutely recommend Ylva's flat. It was very cozy, spacious and "hyggelig". We stayed there for 5 nights over Christmas with 6 adults an 1 toddler. 2 adults slept in the children's room which was absolutely no problem. Our one year old daughter also loved it there, she could move around freely as there were no stairs and she liked to play with all the duplo.
Communication with the host was easy and we always got a quick response. Ylva and her husband were very friendly and helpful. The flat was very clean and there were two bathrooms - both with a shower, which was great with so many people.
The streets were quiet although we were so near the city centre of a capital city. We could walk to the city centre (approx. 20 minutes) and everything else like supermarkets or bakeries were also within a short walking distance (5-10 minutes).
We had a great time, thank you and "tusen takk for oss"!
