I had a great time with Efendi Travel, I booked their service via emails before I travelled to Istanbul. They are very helpful, friendly and cooperative. The company offering great customer service and the taxi driver was prompt, professional, polite and the cab was clean.
I used Efendi services 2x on a recent trip to Istanbul and was very pleased with the prompt email follow up confirmations and on time pickups. In the most recent case, Turkish Airlines permitted changing arrival airport from SAW to IST--and Efendi was able to accommodate the new pickup location with only 60 minutes of advance notice.
We chose Efendi Travel (Tours) in a round about way via TripAdvisor due to all the great reviews, but actually through an entirely different organization. We were not steered wrong. Although this was not a lengthy nor difficult job, we were pleased that they were friendly and professional. This was an airport transfer from the airport to our hotel in the Beyoglu area in Istanbul. We were traveling through Turkey for 3+ weeks and didn't want to deal with heavy luggage and transfers on busy public transportation. Efendi travel came through with no problems.
We booked transfers for our group of 20 people and city tour. Managers were responding all questions immediately by email, prices for services was cheap. Drivers were ontime at the airport and hotel, buses are new and very comfortable, guide was very good. Totally 5* VIP service. Highly recommend it to everybody.
Efendi travel was always quick and professional in their email response to me as I planned the trip. They listened to what I was saying and they came up with a plan to show our team the most of Istanbul. They were willing to accommodate any changes we wanted. They were going to pick us up at the airport with a sign, take us to our hotel, pick us up later for the tour, pick us up the next day for another tour, and then return us to the airport.
