He was the eldest son of the couple, having one elder sister"...could you change to but had one other sister? Not done but clarified
The statement about swimming and horse-riding seems out of place in this sentence. Perhaps you could say something to the effect that his education included athletic activities, as well. Done
The second paragraph in this section contains a few sentences that need grammar checking and also a quick check to make sure they don't incorporate too many clauses. I do not understand the last sentence, about looking "at east," unless it's supposed to be "at ease." Done
Please include the name of the French minister interrogated by Metternich. If you can, also include the names of the legislators. Was this, by any chance, the French turncoat Dumoriez?

Remaining sections
Although the article meets GA criteria, as explained below, I may add more comments here within the next few days to assist in making general corrections.
My major concern
My major concern is the first paragraph of Historical assessment. I understand that the comments in this paragraph are supposed to be from the point of view of an unfavourable historian, but unquoted phrases describing a "pointless" struggle and "a more enlightened chancellor" do not sound acceptable here on Wikipedia.
General comments/concerns
Section headers eventually become quite small and a little hard to differentiate between. I understand this is necessary given the additional level-two sections at the bottom, but it's just something I noticed.
There are more than a few redlinks in the page. Again, they're probably necessary, but it detracts from the overall appearance.
Sourcing is excellent.

This article is well-written and, with the exception of the errors outlined above, is ready to be listed as GA. In order to make A-class or FA, corrections will need to be made around the article, again as listed above, but I am ready to pass this as soon as my major concern is addressed.
