Get the insurance. The negative reviews are accuate in that they do not take any time at pickup or dropoff to inspect the car, and just tell you that they will "email you an invoice for any damage". But they are very very clear when you go to pick the car up that if you refuse their insurance you will be charged for every single scratch, chip, dent or crack. Since they don't actually inspect the car with you, you are likely going to pay for any small detail on the car. So even if you have third party insurance, just avoid the hassle and pay the insurance (online ahead of time - it's cheper) and you can get in and out of the lot quickly. Which, as reported, is hard to find. The rental kiosk is on the train platform, then you have to walk down the street about 10 minutes to the lot - which is very hard to find when you return, and Google maps won't help.
Hidden fees and cumbersome process
Great experience renting. Everything was as expected and staff were friendly and prompt.
Ljubljana office said there was a Dropbox in Prague. THERE IS NOT. But we spent an hour—at midnight—looking for it. We will see if a discount is forthcoming.
The car (Skoda karok) was great! We needed some flexibility with the pickup in Ljubljana airport because our flight was delayed. We didn't get it from the first representative we encountered, but after requesting to speak with the supervisor we were able to find a solution. Returning the car in Ljubljana train station was a little of a treasure hunt, and the parking place was filthy and creepy with rats running around, but the office itself was clean and nice.
Easy location at the bus depot in Ljubljana, super friendly and helpful staff, v clean and tidy car, perfect to run 4 large adults around the city and country side for the day and all at a great price of 63 euros (excl. insurance which we had elsewhere). Driving in Ljubljana and surrounds is v easy
