American stay in paris for a few weeks?

hey everyone, curious to now your thoughts on this: I just finished my third year of uni and am done for the summer. I also just won this (fairly generous) writing award and I know for certain I want to use the bulk of it to visit europe. i've just never been abroad and wanted to do something interesting and fun for myself. I thought of just visiting for a week or two various cities, using mostly-if not only-trains. i'm also lucky enough to be able to live at home so at the moment I'm not worried about other finances lol. but then the idea came to me yesterday that I could just stay in paris for about two weeks, maybe three; I could still always use the train to visit nearby cities. I'm at around b2 level of French, enough to get around easily I believe, and I feel it would give me the perfect mental space to just work on my project during the time. ofc I'm aware paris isn't inexpensive, so I'm open to any and all thoughts!
