I'm planning a move for Sept. I've gotten many recommendations and quotes. Here's what I've learned:
english online interface, english office workers, they get you 5 quotes from companies they have supposedly checked out. They also follow-up and answer any questions.
german online interface, gets you 5 quotes
german interface, gets you quotes
reviews of removal companies and cleaning companies.
* Have your top few come visit and give you a customized quote. They will vary about 25% plus or minus.
* Make sure to have insurance, abgabegarantie (garanty at time of handover to old landlord for cleaning), and ask to be billed for services instead of cash on moving day.
