This was not a good service in November when the departure terminal was not busy and the water taxi's were readily available. It is about 2 times the cost of a standard water taxi. The only reason to use it would be in VERY high season and you want to avoid a long wait. The persons from our cruise who used the standard taxi's got them sooner and spent half as much.

This was not a useful service. The port is only a mile or two from the downtown hotels and a taxi would have been a fraction of the cost.

This was a useful service. The arrival lounge at Istanbul airport was a zoo, it was nice to have someone there who knew your name. A bit of a glitch in that Viator uses another service with a different name and it is initially confusing as to whether it was the right person or not.
