Although the cost of living is quite high in Paris compared to other cities, but i don't think it's something to be discouraged about. I mean for me, you can stick to your budget it just takes a resourcefulness. just put it this way, if you know your tight on budget, don't go eating in restaurants; you can always go ahead and cook your own food right? you can always save big money on that one. the first few weeks would be rocky since you will still be adjusting to the place and cost of living and stuff, but after that im sure you can find your own tricks on how to save money!
