Iben's place is a great deal, it's a great location and value for money. My family (5 of us) spent about a week at Iben's place in Nørrebro. It's within walking distance to most of the attractions, close to transit and about 30 minutes away from the airport by Metro + bus. Unfortunately, we took a taxi to get there since we had quite a bit of a luggage and the taxi stopped about a km away from the entrance (construction/roads being blocked around the area). We took one of the entrances marked "7" (Arca) but it was the other entrance, Iben's partner was prompt in assisting us to the right location and even helped us carry our luggage up to the apartment. Some things we liked at the apartment: the record player, the Handmaid's Tale illustrated version, the Andersen/Maillard pastry place close by. The rest of the family didn't have any issues, but the bedding in the smaller double bed (the quietest room facing away from the street) did cause my dust allergies to flare up. It was manageable with antihistamines but worth pointing out if you're sensitive to dust like I am.
Overall, I think Iben's place is a great bargain and a very convenient location. I'd stick to public transport to get there and would stay there again if I were in the area. Iben also recommended a few restaurants, things to do around the area and was prompt in responding.
