Be cautious !
I used Quick Office for one year at their Hyllie Eden Malmo location, which was later acquired by Mindpark. I gave early notice and ended my contract according to the rules and laws.
Be cautious: they take a 7,500 SEK deposit, and it's been over 4 months—after sending more than 10 emails, I still haven't received my refund.
Now my lawyer is preparing a case to report this to the relevant authorities to get the deposit back. It's really unpleasant and unfair to have to fight just to get your own money returned. This kind of behavior is something you'd expect from scam companies, not professional office providers. The office space itself was just okay—not worth the hassle in the end.
