I will be arriving to Istanbul end of the month. I have a room booked at the Holiday Inn Sisli and The W. Which hotel do you prefer and what area would be more central? The reviews for the Holiday Inn indicate it's a 5 star property, is this really the case? I am just a bit nervous since this my first trip to Istanbul. The W didn't score as well on reviews compared to the Holiday Inn. I have no idea where to stay. I will be using points at either property so rate is no concern.
