They built too much of them, they are overpriced, and they aren't built very well. Tons of complaints, I've heard. Also, "luxury" just simply means granite countertops, stainless steel fridge and new. Besides that, they are overpriced boxes.
Seems like more and more millennials are moving out of NYC anyways because of the high prices.
