Just as an FYI, this property is usually pretty good at accommodating phase requests, so I wouldn't worry too much about which phase you buy in! That being said, we own in both, and I personally prefer Key West. It was built a few years after Bella so it's technically newer, although Bella has been recently renovated. I still find the decor to be brighter and more modern in the Key West phase. Bella's renovation was underwhelming in my opinion-keeping a lot of the old elements like the counters, backsplashes, older bathroom tiles etc. Plus those buildings are pretty old and the infrastructure is starting to wear. You can take a look at Starwood's site if you want to see more of the interiors (

In terms of layout, which you can also view on the site above, I believe Key West offers a bit more space, and it also features an extra half bath in the one bedroom premium side which is very nice to have.
As for the amenities, both have pools and fitness centers. Bella has the main pool (big waterfall) and a quiet pool, a little shop, a cabana pool bar as well as the full service restaurant. Key West does NOT have a food/beverage outlet by the pool, although it does have a rec center with an arcade and fitness center. I find Key West to typically be much less crowded and quieter in general which is why we really prefer it. The one pool is large and nice, and I rarely have issues finding seats or tables at that pool. You can also always walk over to Bella or St. Augustine (5-10 min) if you want a more exciting scene and dining options.
So I would definitely recommend Key West, but if you have any more questions let me know!
