I've reviewed maybe 8 airbnbs, and never given lower than 5 stars, so I'm not a harsh critic.
It was a fine stay, the location is absolutely perfect, and it absolutely would get the job done as a place to stay while in Chelsea, but it was just not quite what we expected.
The bathroom has wallpaper tumbling off the shower walls in a way that gets on to your skin during showers. There was no soap/body wash anywhere. The hand soap at each sink was incredibly watered down. The TV had no instructions for setting up and wasn't connected to the wifi properly. The actual space is incredibly small (I was with someone who spent time in plenty of Chelsea apts, and even for Chelsea, it's just very tight).
Overall it felt like extra care hadn't been taken to make it set up for guests. And if you're considering booking, just envision the tiniest possible interpretation of the photos.
Overall, I have to give 3/5 for the reasons I described!
