The rental itself went smoothly. A nice lady from Portimaos explained me everything and showed existing damages on the car. But it's hard to find the drop-off location (it's in a hotel and you need to ask at the reception to enter underground parking). I received these instrucitons 20 minutes before drop-off so I didn't have the chance to read the email and lost 30 minutes to find the leave the car :( Apart from that I can recommend this company.
Very friendly and competent staff, car was in excellent condition, prices are fair
