I certainly have mixed feelings about this hotel. While the immediate surroundings are very nice it is however located far away from the major attractions. Also a major issue is that getting back to the hotel in the evening with a taxi is practically impossible as the traffic tends to be very bad.
The hotel itself is nice. Since there is only a small part of the hotel that looks on to the Bosphorus most of the standard rooms have a street view. Anything else will cost you more. This is the kind of hotel pricing that I find appalling. Just because a hotel has a bad location should not mean that the guest has to pay much more so they dont here the garbage car every morning.
Its a 5 star hotel but there is no swimming pool. Most hotels have this in Istanbul.
The only really amazing thing in the breakfast area where you can sit out on the bosphorus and have your meal there.
Would I come back here? No. For this price there are far better located hotels in Istanbul with better facilities.
