We do feel a little silly fawning over a fake apartment that was created as a promotion for a movie, but at the same time, this is a Teenage Mutant Ninja turtles themed apartment and perhaps it's best not to look a gift horse in the mouth. (Also, though we haven't seen it, we'd imagine that this apartment is much better apartment than Teenage Mutant Ninja Turtles: Out of the Shadows is a movie.) The underground lair is available for one night only, and only if you win some sort of contest. As far as windowless apartments go, this is pretty much the pinnacle.
