So I ended up in a lucky situation where I will be going to France for two weeks end of July, with a free place to stay in Paris. Ended up being able to stay at a friend's apartment in number 16 arrondissement, apparently it's close to the Champs Elysee. I will have a friend / guide for a few days but will be looking for tips on the other days. Other than the obvious like Versailles, the Louvre Etc. Any interesting suggestions? Also totally open to leaving Paris and going to other areas. Thanks for any insight!
