After having worked with some rental agencies in Paris, this one was an unpleasant surprise. It seemed like they have an answer service with one agent who keeps her phone off. We were looking to rent an apartment for one month in Paris. Somehow agency fee was 40% of the total rental, and not the customary 5%. When I mentioned that to her, she never realized that and was surprised by the percentage. It was clear that she made that agency fee up.
Then, you pay directly to the owner, including deposit, which was 100% of the rental, which she later got reduced to 50% of the total rental. What's the point of the agency if I have to pay directly to the owner? Seems like a high opportunity for scams. And, payments must be made by travelers checks. I'm not even sure where you get those checks from these days, but then you are essentially shipping cash overseas to an unknown "owner."
Then, this agent said these owners are reliable because she rented one particular apartment over 53 times. She made that number up, again. It is highly unlikely that this long stay apartment could have been rented so many times. These are monthly or annual rentals, not daily!
Overall, I did not feel comfortable working with this so-called "agency."
