As Safetymom said, there are bus stops in each village so you're close to a bus stop no matter where you stay.
We've stayed in both the bottom and second floor rooms and have had no problems, whatsoever, with noise. The stairs are not real steep and, since you don't have small children, you should have no problems going up or down them.
I have lots of pictures of the rooms, the pool, the marina and the resort grounds in my trip report. If you'd like to take a peek, just click on the link below.
