After a very long and frustrating search where I encountered, Nigerian rental fraud scammers and way to many Makelaars demanding €50 for nothing! €50 to get access to their website which yields, zero call backs , zero service and way too few apartments for rent, I finally found a straight up no BS estate agent/ Makelaars - Riva Rentals!
Their approach is simple, old school and effective. They post apartments for rent on the internet, if you interested you contact them and make a viewing appointment, (no money is requested at this stage) if you like the apartment you express your interest, give them the relevant documentation so that the landlord can make a decision.
Once accepted you pay Riva a reasonable administration fee, negotiate the fine details, pay the deposit and rent, no time was wasted and no funny business from Riva Rentals staff, Valerie van der Wilden carried out her duties efficiently and in a very professional manner.
Transaction started and completed and I moved in within 4 days. Highly recommended!
