We had a fantastic stay in Søren's flat. The location could not be better, it's next to the Metro (direct line from the airport, relatively cheap and about a 20 minute journey) and close to many of the main tourist destinations and shops. If you're going to Copenhagen for the food and drink you're well located for key destinations like Ruby, Torvehallerne and Paper Island and it's just a short hop on the river taxi to the Opera for Noma. We got an Uber to Höst but could have walked it. We walked almost everywhere.
There is a trade off in location because it was very noisy at night (nightclub and bar just outside) and early in the morning (building work) - this would have been worse because we arrived to an unseasonal heat wave so the windows were open - but it didn't matter to us and we would stay again. It might matter to you if you needed to get up early for work or if you needed peace and quiet.
The flat itself is well equipped, wifi is good and the bed is very comfortable. I would agree with the previous comment about the shower but it was fine. It is very tiny for a self contained flat so if you are very tall (or fat!) it might not be so comfortable but it feels large when compared to a standard hotel room to two small-ish Brits.
Søren met us at the metro and showed us to the flat. He was polite, friendly and understanding when our flight was delayed and best of all very relaxed about check out times. Some AirBnb places are like mini guest houses with lists of instructions, lots of local information and strict check out times but this is not one of those. It's much more relaxed and feels like you've been given the keys to a mate's flat for a couple of days.
Highly recommended and would stay again. Had a wonderful time in Copenhagen and thoroughly enjoyed ourselves.
