Great Jones Aly, NoHo

Great Jones Alley is one of the few alleys in lower Manhattan that's not actually a desirable address. Most of the alleys (especially in the West Village) are prime real estate due to the privacy and the feeling that you're a bit removed from the city traffic. This alley looks exactly like what it sounds like: an alley. It's gated off now and just looks like a long parking area off of Great Jones Street. It was built in 1825 and used to be much longer than it is now.
There are a couple of businesses (I believe there's a tailor in here) and some apartments. But, I wouldn't want to live in them. I love Great Jones Street but the alley is really creepy and seems dangerous at night. You compare Great Jones Alley with something like Patchin Place and you can't help but wonder why anyone would choose this alley. It's gloomy and looks like a drug deal is waiting to happen at any moment.
The good news is that if you do live on Great Jones Alley, you're just off of Great Jones Street which is a great little street. The bad news is that you have to walk into Great Jones Alley at night every day.
