The fun question is, what exactly is connected to those sensors and experiences them and where is the location of that thing?
It's like we're sitting with a VR headset in our brain, playing that game we call life. But, where exactly are we and how is that headset connected to our sensors?
Again, your body.
Think about it. Your body is experiencing what your brain has generated out of your sensory input.
You don't need a homunculus, you are a body. You are your body and there's nothing else to you.
It's like you're asking why is this computer that I generated this data visualization from this data on this computer displaying this data visualization on this computer. Umm, because that's what you asked it to do and that's the default? For anything else to have happened, you would have had to redirect the output to a network and then go receive it on a different computer.

You are your body.
> So - does water flowing down a hill have a perspective? Where is it located?
Why would it? Does it sense and produce a mind? Not that I'm aware of. You could go the pansychism route if you want though. See David Chalmers or something.
> can I say that I'm any less the water as I am my hands, even though I'm controlling the water, getting feedback from the water, subjecting the water as much to my nervous system as I am subjecting my hand itself?
According to enactivism, no. [1] In general, see embodied minds theory. [2]
> Why would it? Does it sense and produce a mind?
I don't know what a mind is supposed to be in this context, or its importance. I don't identify my perspective with my thoughts. My thoughts are something a body does. My perspective is just my location. After death, my thoughts will cease. My location will not change.
If you are going to ask questions, you should at least be able to justify their relevance, if asked.
