About Rentrium
Cars from Greek rental companies, booked directly.
We are a marketplace. Rental companies across Greece list their own cars, set their own prices and terms, and hand you the keys. We built the part in between — and the rules about what a listing is allowed to claim.
What we are
A marketplace
Every vehicle here belongs to a rental company that lists it, prices it and hands it over.
Local companies
Rental companies across the Greek regions, listed on the same terms as each other.
Your own language
Most of the people who rent a car in Greece do not live in Greece, so the whole site is published in every language below.
How booking works
Choose a region and your dates. Every result is one particular car with its own availability, its own price and its own photographs — not a category you are assigned at the desk.
Depending on the rental company, you pay online when you book or at its desk when you collect the car, and the page you book on tells you which. A booking paid online is confirmed as soon as it is paid; one paid at the desk is confirmed straight away or once the company accepts it. You do not need an account: a booking reference is emailed to you, and that reference is what opens the booking or cancels it.
At the desk you show the reference and your driving licence. The security deposit is arranged there, with the rental company — we never charge it, and the amount is on your booking before you book.
What we hold ourselves to
Each of these is a rule the site enforces, not a sentiment. Where a claim would be true only sometimes, we have left it out.
One total, before you book
The total you see when you book already includes any extras you choose and any delivery fee. If you pay online, it is the amount charged to your card, and we never charge a second time for the same booking.
We add no young-driver or age-based fee. A driver age you give is passed to the rental company; it never changes your price.
Our commission is not on your bill
The rental company pays our commission, on an invoice we send it. No platform fee is ever added on top of the price you were quoted, and none appears on your booking or your receipt.
A photograph, or a picture of the model
Where a rental company has photographed a car, you see their photographs of it and nothing else. Where they have not, you see the catalogue picture of the model — and the listing says which of the two you are looking at.
We do not inspect what a picture shows, so the label is about where the photograph came from, not a verdict on the car.
Reviews you can trace to a rental
Every review here comes from a booking with this rental company that was confirmed and never cancelled, written by the customer whose booking it was, from an account with a confirmed email address, after the rental period had ended.
Cancelled bookings (including ones the company reported as a no-show) and bookings still awaiting payment or the company’s confirmation cannot be reviewed.
A rental company cannot hide, edit or delete a review written about it. It gets one public reply, and it cannot change that either.
A rating that cannot be bought
The Highly rated badge is worked out from a company's own reviews and awarded automatically. It cannot be bought, requested or switched on, and it never changes the order of your search results.
Cancelling cannot become a bill
Cancellation terms belong to the rental company, and they are copied onto your booking when you book — so a change they make later cannot change what you were promised.
Cancelling online can reduce your refund to nothing, but it can never create a charge.
Renting your cars out?
List your fleet and keep it yours. You set the daily rate and the seasonal rates, the deposit, the free-cancellation window and what a late cancellation costs, and your own rules about how short or long a rental can be and how much notice you need. We do not price your cars.
Bookings, availability, off-road periods, photos, desk walk-ins and what you have earned all live in one portal, with separate logins for counter staff and for whoever keeps the books. Our commission is invoiced to you once a month and is never added to your customer’s price — and neither a walk-in you enter at your own desk nor a booking a customer makes on your branch page or through its QR code carries any commission.
