My experience with W Istanbul was great. I stayed in a Fantastic Suite which was quite small for a suite, but had the typical brilliant W design and with some new details there isn’t in the other W’s. The service was very good and up to the standards I’ve seen in the other W hotels. I didn’t eat in the hotel, but there is lots of choices within walking distance of the hotel. The internet was complimentary because of my Platinum status with Starwood and was quite fast during my stay. My conclusion is that it’s a true W experience and highly recommended as one of the best places to stay in Istanbul. The Istanbul Edition was my favorite by far, but W is surely a great place to stay as well.
My opinion: Great experience.
