At the Easirent counter (in Dublin), I was unable to pay the deposit with my Fineco credit card because the merchant's terminal did not require the PIN, and my bank (rightly) blocked the transaction. In fact, the deposit was 2,900 euros (an outrageous amount...). Therefore, to overcome this issue, I was forced to purchase full insurance at the Easirent counter, which cost me 480 euros compared to the 83 euros I had paid with DiscoverCars. After opening a claim and sending about 12 emails in which I proved my case, it was not possible to recover the full amount. If you can, avoid this rental company. I get the impression they do this to sell you their own insurance. In fact, I have read similar reviews on DiscoverCars.
