Tricky agency
Tricky agency run by arrogant kids with an attitude.
Be careful what you sign with them. They ask you to sign an unfair exclusivity agreement (without signing it back) and also ask you to deposit money to their account as "confirmation deposit" where they are free to deduct any expenses they deem appropriate, even if the deal does not go through. Although the exclusivity agreement, they keep advertising the same property to many buyers and negotiating, till last minute, and easily leave you stranded without any hint of remorse. To be avoided especially if you are a foreigner and do not speak german. Recently their shop was defaced by other unhappy customers. The market in Berlin is very competitive but luckily there are better, more honest, agencies to work with.
