Id put it on the other side of the bridge closest to yr house!! You'll check it everyday, but it won't be in the way either (unless you've other plans!!)
Looks like someone's living up at the top left, but I'd suggest at the very top left. It'll be out of the way and it's kind of a private spot sort of like if you were actually camping you'd look for a private spot. Mine is at the very top left as well.
Also I think the bottom right would be very ideal as well right next to the bottom of the river in a corner which is very close to your house.
It depends on how you use it.
If you're going to check it as usual and you don't TT or soft campsite reset, then put it anywhere, or near your house maybe. If you're going to soft reset, put it on the top left because it'll make things WAY easier.
