No, but its day is essentially the same as its year, so the sun wouldn't appear to move in the sky, and the planet has a day side and a night side and the lack of light changing would be a tiny irritation. But if you colonized it you'd sleep indoors anyway and artificial lighting would provide a normal sleep cycle.
