Secret? Maybe it depend on who goes there? I dunno, i'm having an argument in my mind about this being secret or not.
It kind of lack the 'garden' feel of a garden. I think it's a bit bland.

Looks warm and looks like the best spot to take an afternoon tea break alone or with someone special. it kinda has a solemn feel to it. like the kind of place you'd expect to find a kind old couple or young (kids) aristocrats of some sort.
I'd love to take a nap there.
