send me an e-mail if you need anything in Istanbul. Are you coming to Istanbul with the last LH flight of the day? at 01:25 (a.m.)? Then you need to pay a lot of money to Taxi. If not you can easily go to city center with Havas Airport Bus. Havas bus is every 30 minutes The last bus is at 00:30 and cost you only USD 3. But do not forget to exchange money before get in the bus. You will see many banks in the arrival area.
