Since I’ll likely be tired from my overnight flight from ORD, I reserved a hotel in Taksim area for one night ($50) for rest or quick naps before I head back to IST using HAVAIST bus again at around 9:00 pm.
Also I would suggest to ensure that the hotel is aware that you're going to check-in at the morning and checking-out in the evening.
