I have been going to Suntide III for several years now and recently stayed in 603 and this one has been my favorite so far. Suntide III has excellent service, covered parking, available grills, umbrellas when requested, and spectacular views.
This condo is now my favorite because it really is a home away from home. It is actually decorated, comfortable beds, flat screens, real indoor and out door furniture (no pvc pipe furniture), and a kitchen completely stocked with a huge fridge and every kitchen utensil needed. We went to HEB before and cooked with no problems and even used the Suntide grill downstairs one night.
This condo is right on the water and its even directly behind the Blue Marlin (the island grocery store in case you forget anything)
