Avoid at all costs. The worst moving experience imaginable.
We hired Flytthem for our move on 18 April and deeply regret it. The movers arrived late, worked painfully slowly, and handled our belongings with zero care; hitting items against walls repeatedly. Despite the move taking far longer than it should have, they tried to charge us an extra 2,000 SEK at the destination, claiming the distance to the elevator was too long. The distance was a few metres. After a long dispute, they eventually corrected the invoice, but only after enormous stress on moving day.
To make things worse, our diplay was damaged during transport despite being in its original manufacturer packaging. When we raised this, their response was essentially: "you should have photographed it beforehand; not our problem." No apology, no compensation, no accountability.
We had also recommended Flytthem to two friends and had a cleaning contract with them. All of that is now cancelled.
In one sentence: Overpriced, dishonest, careless with your belongings, and completely unresponsive when things go wrong; save yourself the stress and book literally anyone else.
