The companies employees go above and beyond to deliver excellent service! The drivers are very polite and professional. The prices are the lowest that I found for private taxi in Istanbul and trust me I have done an extensive research looking for the best deal. The owner was in constant communication to ensure that the service is timely. He was the only person that I had contact in the city and he was very helpful to advise so much useful info for the trip (places to see, restaurants to order food from, etc etc.)and even checked how my return flight was. Absolutely the best prices, great service and communication! Highly recommend!
