The pro of this place is the location, it is excellent, near the metro and bikes to rent plus convenient to most of the top sites in Copenhagen. The cons are lengthy. I stayed in summer and the flat was hot with no AC and no fan so I left the windows open which allowed all smells and noise into the windows, people were using BBQs on their decks, smoking cigarettes, etc. so this and the noise of their TVs, laughter, babies crying etc. was unpleasant. There are no curtains on the glass door leading to the deck in the bedroom and only the lightest of gauze curtains and white shades on the other windows so the natural light and all of the lights from the neighbor's flats pours into the bedroom, I slept with a t-shirt over my eyes the whole time I was there. Bring earplugs and a sleeping mask. The neighbor right across the way has fairy lights all over their deck so there is no escaping light.
There was one hangar so my business suit and dresses had to be draped over furniture, no cutting knife in the kitchen or salad bowl or anything resembling an actual "cooks kitchen" so making a meal was challenging and frankly, that's the whole point of renting an airbnb (for me anyway). For the price of a luxury hotel I expected a tea bag or a few grains of coffee to make a cup of something when I arrived but the cupboards were bare, literally salt and pepper and that's it. It doesn't feel welcoming to say the least. Bring your own soap and washcloth or sponge too and the shower is bizarre, with no curtain or door it's pretty much a magical act to not soak the entire room with water while trying to get clean. I could go on but what's the point, I was sorely disappointed after reading the mostly positive reviews, I expected something better and more comfortable. Also to note-there IS a lift but you still have to go up a flight of stairs and there are also 4 or 5 very steep stairs up to the door of the flat so people with small children or physical handicapped should know this.
