The process was quite convenient. They asked for the order, driver's license, passport, and notarized documents, then only inquired about additional insurance (I guessed, as my English isn't great). I declined, swiped my credit card, got the keys (which had the parking spot number), and left. Originally booked a BMW 3, but got a new Lada with only 1700 kilometers. Returning the car was also very easy; I just said 'done' to the staff (non-native speaker), they checked the car with a device, and it was fine. Back at the office, they gave me a receipt.
