What residents like
- ✓Among the most exclusive addresses on the island, with bay views and finishes that match the ultra-luxury price point
- ✓Controlled access and concierge service appeal to renters prioritizing privacy and security
- ✓Extremely low turnover and strong resale/rental demand reflect a consistently desirable building reputation
Common complaints
- ✕Rent is out of reach for the vast majority of relocating renters; this is a tower for high-net-worth tenants, not typical apartment seekers
- ✕Individually-owned units mean furnishing, finish quality, and lease flexibility vary tenant to tenant
Our take
Grand Bay is a landmark ultra-luxury condo tower on Key Biscayne's bay side, renting out units well into five figures per month. It anchors the top of the island's rental market and is realistically only relevant to renters relocating with a substantial budget.

About these pros & cons
How we build these pages: we read publicly available resident reviews (Google, ApartmentRatings, Yelp, Reddit and similar) for each community and summarize the recurring themes in our own words. We don't copy review text, we don't display star ratings we didn't compute, and no complex has paid to appear or to have anything removed. Cons reflect what residents report — experiences vary. Rent ranges come from public listings and change often; always confirm current pricing, fees and policies with the property directly.
