Calling Paris "bland" and "boring" has got to be one of the hottest takes in the history of online takes. I usually remove a downvote from comments when I reply to them but I will relent from doing so in this case.
Perhaps it's just because I've grown up in the UK, surrounded by gothic and medievel buildings etc so a lot of Paris is just more of the same, but for me my weekend trip to Paris about 10 years ago ranks at the bottom of all my holidays. I found Berlin far more interesting and exciting than Paris. There are some lovely bits of Paris, but huge swathes of it are traffic stuffed concrete ovens during the summer. The Arc de Triomphe is surrounded by a 6 lane roundabout, which is fun to watch for a bit, but rather detracts from the ambiance of the site.
