It was a nice flat, and a good location, but it is not a flat for 6 adults.
It was only set up for 5 people - There were only 5 single duvets and towels set out. We notified the host of this on arrival but there was no response for 3 days. The 2nd bed and sofa bed are both small and really tight for adults. We had to move a spare mattress into the kitchen/ living room for one person to sleep in, and in the main bedroom we'd to use a single duvet sideways with a sheet over our legs and feet, with towels on top to keep warm.
We were given wrong information for the WiFi which never worked. There is no storage, and it appeared that there were bundles of dirty bed linen under the main bed. We didn't get information regarding check in until we arrived in Oslo, and check out until after 10pm on the night before we left, after 3 days of no contract.
