We had a great time in the basement apartment, it was very clean and in a perfect location for us. There's plenty of space and the sound system is a great addition. I'd note the bathroom and kitchen are separated by a curtain and share a sink (this wasn't immediately obvious from the photos). Also the kitchen did not have an oven as shown in the photos.
Regardless, this is a great place to stay to explore New York, difficult to find better for the price!
