Sorry! I had not seen your question for me for some reason. If you want to contact me directly in the future, if you go here:http://www.justanswer.com/profile.aspx?PF=23511658&FID=12299

On the "Cheap-meter", from 1-10, it's an 11. It has 3700 members and it's an active community that has social meetings as well.AirBnB.com
is similar, and doing things that way will run about $40 a night on average. Cheap? That's $1200/month, which I suppose for anything near manhattan is inexpensive. It's less than I paid for my 1 bedroom on W45th street 10 years ago, but I still have a hard time calling $1200 "cheap".

And finally, this site allows you to actually rent other people apartments. And that can be nice if you'll be there for a while. There's more privacy, you can cook your own food, etc. These change constantly, but as I look at the page, there is one in New York for $60/night. And unlike with hotels, that's the final price, so it's a lot cheaper in the long run.Guesthouse Network
I hope this helps!
