Thanks for all the suggestions. I emailed several airport transfer companies recommended from tripadvisor website and forum. I chose the one that replied to me the fastest and with most details and professionalism, which istanbultransfertour.com
Everything went smoothly. I arrived in Istanbul, saw my name on the card, got on the mercedes vito and arrived at hotel without problem. I would recommend istanbultransfertour.com to anyone looking for airport transfer.

TRANSFER FROM THE AIRPORT: Last time we went by metro and tram, which was very easy, but this time we arrived late at night and thougt it would be easier for us getting a transfer direct to our hotel, but after having read about the taxi scam on this forum, we were worried using transfer or taxi, but decided to try booking a transfer from the istanbultransfertour.com, I have read about on this forum
and what a good experience, the driver was waiting for us with the signboard with my name on, and he was a gentleman, very polite and drove us safely to our hotel, he was a fine representative for the company - THANK YOU. - it is good to know that there are honest transfer companies.
