I used to live in the District Apartments in front of Vista Cay. The area is very nice; just some of the residents sucked, but you'll find that anywhere. Vista Cay has a nice pool area and jogging trail around a lake. Depending on what direction your unit is facing you can see the Seaworld fireworks at night.
There is also a Publix supermarket within walking distance and a nice little pizza place called NYPD Pizza.
Traffic on that section of Universal Blvd is next to nothing unless there are any events getting out at the Convention Center.
