While not the first underwater hotel, the one being built in Istanbul does promise some questionable views. The seven-story hotel is being built in the Istanbul Bosporus Straight, where the visibility underwater is allegedly only 10 feet. So you can forget about any view like that one in the picture! You won't be able to see shit. Well, except the pervert with an underwater camera snapping pictures of you. And yes, I agree, that sounds almost too romantic.
