Dirtiest hotel I've ever stayed in. DO NOT STAY HERE.
One star is generous. Though very well located please heed my warnings and book a stay elsewhere. My friend and I payed close to 150$ a night for a room unfit for a rat. Sure, the room was small, there was no view, the furnishings were sparse and the walls were scuffed and dented and spackled sporadically. I wouldn't have cared one bit, had it been somewhat clean. 
Unfortunately, there was crumpled toilet paper, and other randomly strewn trash under the bed. There were crumbs and what appeared to be blood stains on the sheets. There were giant dust bunnies, cobwebs, and little curly hairs throughout the bathroom. Oh, and exposed electrical precariously close to the shower. 
I have stayed in 10$ hostels throughout Europe that are immaculately clean. There is no excuse for the Manhattan Broadway Hotel. Do not stay here.
