Albertslund lies in close proximity to Copenhagen, so there are several possibilities for good and cheap accommodation. However, the closest is probably Wittrup Motel https://www.wittrupmotel.dk/en/. This is preferable if you need a bed.
For the asketic participants who don’t need such luxury, a nearby school has promised accomodation on the floor for free, BUT due to you-know-what we’re also working on a plan B. The school has showers, we hope plan B will too.
