My friend and I stayed at the Northwood Lodge on a late September weekend for a wedding in Monte Rio. All the lodging in Monte Rio was already booked. We were not unhappy with our choice; it was a good value, as we were not spending much time at our lodging.
The place is actually much more attractive in real life than in the website photos...at the foot of towering redwoods, with well kept grounds and a very pleasant pool. Our room was clean, quiet, and smelled nice. The bed was comfortable, the bathroom was new and well appointed. I was able to make tea in the morning (very important!)
It is a simple motel, and a good place to stay if you don't want to spend too much, and there are myriad things to do very nearby. The ocean is about 10 minutes away, and Monte Rio and Guerneville are full of charm.
