Let's start with the ending: We had a VERY NICE time here and would DEFINITELY stay here again. :-) 
The area is rural and GREEN. A town is 8 miles away. :-)
This 3-story building has a basement accessible only from the back/water side. You park at ground level but stay in the part above the boat area, which is like a garage (with lots of windows so you can see what's inside).
You go up stairs with about 15 steps. I mention this because some people said the steps were tough. They are a little steep, so don't try to carry 2 suitcases with you up the stairs!
There is a nice size deck on the side where you park. I sat out here some, especially at night. The stars are impressive! The moon was, too.
There is a small deck area on the water side, and I sat more on that side. Though it is the water side of the place, you are not on the water. There are evergreen trees blocking most of your view but you can see the water. I sat out here A LOT and just listened to the birds and the bell from a buoy in the water (I think). 
On one night the moon was shining bright, and the whole "bay" lit up. I got some really impressive photos!
There were 2 of us on this trip. The bedroom is a nice size, and the bed is more than comfortable. The kitchen is just right and has all the pots and pans and bowls you'd ever need. (Careful: the plates do not appear to be microwavable, which I learned by read the small message on the back of the plates.) We prepared several meals here while on this trip.
The TV has lots of channels for you, so that's all good. 
The bathroom is small but adequate. The shower area is small, but as someone who has had several older homes redone over the years, I think the owner has been very creative in how this shower space is set up. 
Things I would recommend: 1. The TV needs better instructions. There are multiple buttons on at least 2 remote controls, and knowing what does what took us a while to figure out. 2. The microwave cooks fast! In fact, I burned popcorn twice before I finally got it right the third time. (The exhaust fan didn't work for us. I flipped every switch I saw but couldn't get it on. Is there a secret I missed?) 
I say these things just so you'll know. The owner was VERY attentive during our stay via email, and I had a number I could have called, too. (Don't worry... no, the owner did not come visit us or bother us, which is always a concern of mine).
In sum, we would definitely rent here again.
