Only if you compare by the room, not by the surface. If you can consider a 3m x 3m a room go for it!

Untrue. I've lived in Paris, London and SF and Paris is definitely the cheapest (even by the surface). I'm paying $1100/month in Paris for a 300sq foot appartment (in a nice neighborhood). I was paying $3000/month in SF for a 400sq foot appartment...

I might be wrong, but I found the kind of room that $1000 pays for in NYC to be way nicer and larger than the one you can get for a similar price in Paris (though the usd/eur has increased 20% since I checked).
