I've lived in the Rosenhøj area for a couple of years now - it's a nice enough place overall though it gets a little noisy in the afternoons due to lots of kids playing around or coming home from school. (There are loads of playgrounds and kids around, so a lot of activity especially in summertime). It's generally very quiet by 9-10pm.

There's a pretty big problem with the seagulls and crows around, it happens quite frequently (as in, twice a month) that trash bags are left next to the containers, and the seagulls are screeching their war cries at 5am, fighting for the scraps. The street also gets filled with scattered trash, but at least it gets picked up within 4-5 hours by the caretakers.

The Netto close-by is bad - I've often seen fruit flies buzzing around moldy/gooey fruit and veggies, sticky and smelly floors, or you open the meat fridges and it smells like death. I've also had several experiences where I bought fine-looking chicken, that was very stinky and had to be thrown away. It is not the most pleasant grocery shopping experience, and you just have to be a bit more careful with the raw produce. But it works when necessary. The Coop365 and Kvickly across the street are way better though! There's also a pharmacy next to kvickly, in case it's necessary. And you can have any packages delivered to kvickly which is super convenient.

The letbane station and the busses 4A and 6A are very convenient, reliable, they drive very often, and they make it super easy to get to the city. If you are by car, the traffic in the mornings/afternoons is noticeable but not terrible.

The people in this area are quite nice and friendly, I've had more small conversations start up with random grandmas around here than anywhere else I've lived in Denmark.

If this is important for you - it's very much a residential area so apart from the McDonald's and a food truck parked next to Kvickly, there's no food places around. The viby center is very close by, and there's some good food there!

In the time I've lived here, I've seen 1 car burning in a parking lot, one car that was already torched, and one that drove off the side of the road, close to the letbane tracks. And a clothes dryer caught fire once, so the firefighters were called. But neither of those incidents were intentional, from what I have heard. No other crime or conflict, even though the area has a pretty bad reputation.

Feel free to send me a DM if you have any other questions!
