I only used Kiwitaxi once time. From Samara Airport to Samara center. I booked a taxi for 4 passengers plus 3 pieces of luggage. Driver was waiting for us, perfect. Obviously he didn´t speak English, only a few words. We reached the car, a SUV, but with a great wheel in the boot of the car. So, our 4 pieces of luggage (one big, two standard and one small) diden´t fit inside. Solution: the two standard pieces into the boot, and the big and small inside with three passengers in the rear seats. Incredible ! Around 45 km. Price was not expensive, but if you book a transfer in the hotel or in Yandex taxi it is even more cheap. Despite all the driver was nice and behaved well
