It is next to the airport but I don't think noise is an issue. The airport is small and I did not notice problems when I toured WP.
There is about 80 2BR units there that are great. A nice pool as well. Ocean view but across the street. There are no natural swimming beaches in Key West.
It is away from the action. There are cabs and a good bus system to get you to Old Town.
If nightlife is key stay at the regular Hyatt or Hyatt Sunset Harbor. Short walk to the action.
