If you are Planning to visit Turkey and looking for sophisticated travel agent i will strongly recommend to visit www.directtraveller.com one of the No 1 and leading Tour Operator offering direct flight holidays in resorts of Kyrenia & Famagusta, Northern Cyprus.

I would suggest you contact Byzas Tours at http://www.byzastoursturkey.com for a quote. Tell them exactly what type of trip and type of hotels you are looking for - They are one of the leading tour operators based in Istanbul for customizing private tours just the way you want and just for your party. So it if it's sophisticated travel you want, they are an excellent choice. We have been very pleased with their personalized service for our trip earlier this year.

Sweethearth - you are right: this is the one forum question where service promotion is asked for. Apologies, please repost your entry below.
However, kindly do not promote on other Turkey related questions that do not ask for Travel agent recommendations! Thanks.
