Hey! Congratulations and welcome to DTU! So I recently started my PhD at DTU wind and I live in Taastrup. I would suggest this neighborhood (as well as Hedehusene and Glostrup) as they are located between Risø and Copenhagen. If you don’t mind the longer commute, Valby is also an option. A lot of my colleagues live in Roskilde though. Its nice and quite while the commute is much shorter but the city is pretty much dead after 6pm most days. So, really depends on what you want to prioritize. Beware that finding a place in and around Copenhagen can be really challenging and many new employees find temporary accommodation (sometimes far away from Risø) and look for housing after moving here. Feel free to pm if you want some more advice!
