I don't see a reason why not to stay at Julie's place. The accommodation is far better than the photos. Super clean super cosy super near to the train station and supermarkets i.e. LIDL, IRMA (walking distance 2-5 mins). 4-5 stations away from central. Most importantly, though I didn't get to meet Julie in person, she was so nice to help up with recommendations in Copenhagen and very very approcable. Super quick response too. HIGHLY RECOMMENDED!
