Treasure Island Beach is a wonderful place to buy a beachfront condo. The condominium complexes are generally smaller than your condo choices in Clearwater Beach or Sand Key. The beachfront condos on Treasure Island typically range from 20 to 40 units although there are a few larger ones like Mansions on the Sea . The area has more of an "Old Florida" feel to it, and there are lots of terrific local restaurants nearby. The typical Treasure Island beachfront condo is a 2 or 3 bedroom unit with about 1,100 to 1,800 sq ft of living area.
