I saw good reviews of Cretarent, but my experience with them was really disappointing.
Was trying to book cabrio for 6 days, reply from Cretarent came after 2 days I've ordered the car from their site - this car is available and I can book it. Same day I replyed that price is good and would like to rent car. No reply after it from Cretarent. After 2 days I've asked again and got reply that the car already booked. I don't think this is nice servise, feel cheated by Cretarent. They are not interested in clients at all.
