Incredibly clean, felt like I was the first person to stay in the unit. There is a train outside that can make noise, but never really bothered me too much, more of a low rumble than loud screeching. Subway is right across the street and the earplugs that are provided come in super handy for walking in that area.
I got a decent price for it, but it looks like the price per night is increasing quite a bit when I looked for an extension so my biggest issue was the pricing, no complaints about the unit itself.
