I'd absolutely recommend staying here! Steve and his wife created a very welcoming environment. The apartment was comfortable and even nicer than it looks in the photos, and had everything I needed. When I had a couple extra requests (tinfoil, additional ice), Steve was very accommodating. Since I was without a car, he even offered me rides into town a couple times (and I accepted! Thank you again!).
Speaking of not having a car, it really wasn't necessary from this location, which as others have said is great because it's away from the noise and bustle of downtown but not actually far from anything. I was able to walk to Thames St., to the mansions, and to the cliff walk. There's a trolley that runs between these locations as well; one of the stops is walkable from Steve's place. I also found a wonderful park quite nearby (Ballard) where I was able to do some birdwatching. I did take Lyfts a few times while in Newport, including once from Fort Adams back to the Airbnb - I had been worried about Lyft/Uber availability, but it turned out to be fine.
Finally, I feel I should mention that I'm a woman and traveled alone, and always felt perfectly safe at the Airbnb as well as walking to and from it.
I would recommend Steve's place to anyone!
