Today taxi regulations permit taxis to be any type of automobile or type of ownership. Furthermore, there is little real difference between renting a car by the hour or day with a driver and taking a taxi, except that taxis are for specific destinations and car rentals are for time.
Many private cars also stop to pick up passengers, often by drivers going to work or on business. Taking private cars for taxis, however, can be risky and is only for the adventuresome who know some Russian. Evaluate all drivers carefully. Travel in two’s and never get into cars already occupied by two people.
Ordering a taxi usually works quite efficiently, even for early morning pick ups. Officially two hour notice is required, but often they come within a few minutes. All taxi services listed below work 24 hours per day.
