This was such a great property for me, my husband and our 2 sons (9, 11). You are right on the beach. Garden City/Surfside is just the right distance between Myrtle Beach (no thanks) and Murrells Inlet. We were there for a Ripken baseball tournament and it was close enough to that, but not in the mess of Myrtle Beach. The only complaint is that the full size pull out sofa was broken (where your pillows would go, it bent down towards the ground). Luckily, my kids didn't care at all. They just put their heads on the other side and their feet sloped down a little. They were so wiped from baseball, sun, and sand that it didn't bother them a bit.
Maintenance was super-responsive to one issue with the dishwasher that ended up being user error.
