Yeah, visibility would stink, not to mention Istambul doesn't really pop off my mind as a place of desire for me to want to go. At least the Fiji place is themed after the tropical feel
All they need is a minor water change, and maybe running a carbon and sediment filter to polish the water a little, and the water will be rated at Jerlov II type for visibility.
i think the room would be cool but there is no way i could sleep in that bed... i can't sleep with the curtains open so a bubble is out of the question.
