SIXT Ireland Reviews 

Check in desk at Dublin Airport went swiftly. The guy that served me (Mukesh) was friendly and efficient. Mukesh explained everything to me without any aggressive upselling. The car was clean and brand new. Returning the car was super quick. I will definitely use Sixt again in the near future.

From the start the employees were overly helpful. I mean they went out of their way to help. In the busiest time of yesr there was no sign of them being stressed which can unsettle the customer somewhat. They were professional as well asking people that were waiting the queue if they have booked in advance in a way to speed things up. I didnt book in advance but still i got a great car very clean and good working order.

Ease of pick up & return.
Friendliness and helpfulness of staff.
Superb condition of car

The staff are professional, knowledgeable and most importantly friendly. The cars are newer than the competitors. Pick up and Drop off is a smooth process. IMO the best Car rental company in Dublin airport.

Excellent: competent stuff, friendly, professionell, not too pushy

Professional and friendly service at a very reasonable price.

The staff at the desk is very important, and Iwana was really supportive and clear. The car was brand new and it's fine to have more options for additional insurance coverage.
People should know in advance that there's a further deposit to pay at the desk . And it would be helpful to have the directions for returning on paper as before.

The booking process was very straightforward online. The people carrier I picked up in Cork was spotless. I tried to change my drop off point, unfortunately the phone support was not great but when I went in to the office in Dublin airport the staff were so helpful. Will definitely chose sixt again!

Great price, friendly staff, brand new clean car and quick pick up/drop off. Would rent with Sixt for next experience

Sixt in Cork are fabulous. Great pricing, happy people, just lovely.

I’ve used Sixth on many occasions this year and I’ve always received an excellent level of service and a very new and well maintained car. Highly recommend the Dublin Conrad hotel office/ location for hassle-free car rental.

The service above all was superb
Alex, the desk agent at Terminal 1, could not have been friendlier and efficient.
From arrival at desk the entire process was complete in less than 5 minutes.
Will be using SIXT again

I’ve always found the Sixt staff to be very friendly, offering helpful suggestions. On my most recent rental occasion at Dublin Airport, they we really helpful, helping me with my luggage, and the installation of a baby seat. Thank you!

Pickup and drop off were quick and easy. Staff were really pleasant and the car was great. No complaints at all.

So friendly and helpful went above and beyond our expectations and problems. Thanks we will definitely be back.

Again a great experience with Sixt car rental at Cork Airport. 3rd year, 2 times a year. Great value for money. Perfect modern car, great help, quick assistance. Will be back in August 2026 for sure. I can recommend.

Excellent experience as a first time user of a car hire company.

Very impressed at the customer service skills the lady at the desk presented at pick up at Cork Airport. The lady was kind, knowledgeable and did not feel pressurised into buying additional add ons. Will definitely use this company again.

The overall booking process was easy and quick to arrange.

Super beautiful experience with Sixt in all ways..everything was very fast,almost new and super clean car,friendly people on counter,fast return...

Perfect flawless service, professional staff, speedy deposit return, easy drop off and pick up.

Very disappointing experience with Sixt in Ireland.
Our holiday was overshadowed by a series of problems that should never have happened with a rental car.
The first vehicle we received had no functioning air conditioning, despite travelling during a heatwave. We spent hours driving in uncomfortable conditions and repeatedly contacted customer service. The situation became even worse when the infotainment screen stopped working completely, leaving us without navigation, music or the reversing camera.
Although Sixt eventually agreed to replace the vehicle, the replacement process was extremely frustrating. We waited several hours longer than promised, losing valuable holiday time.
The replacement car was then delivered with only half a tank of fuel, even though we had already paid €80.37 for the Fuel Purchase Option, forcing us to spend an additional €28.63 on fuel ourselves. It also had pre-existing tyre damage that was not initially recorded on the rental agreement, and we had to insist that this be documented to avoid being held responsible.
Throughout the entire process, we remained patient, polite and cooperative. We reported every issue immediately, provided photos and videos whenever requested, and followed every instruction given by Sixt.
What disappointed us the most was the lack of transparency afterwards. We were repeatedly passed between departments, had to chase for updates ourselves, and the final invoice still does not clearly explain the charges, discounts or the refund calculation. Even after asking for clarification, we have still not received a detailed breakdown.
Mechanical problems can happen. What matters is how a company responds. Unfortunately, in our case, the communication, customer service and follow-up fell far below the standard we expected from an international company such as Sixt.
We cannot recommend Sixt based on this experience.
