Overall, our stay was good. The house has a great layout for families. Plenty of space and very nice to have a full size washer/dryer to get rid of salt/sand! It's a close drive to the beach... would be a tough walk with all of your beach stuff.
Few things specific to our stay: when we showed up, the kitchen window was stuck open about 5", both master bath sinks were broken (one clogged, one had a broken stopper preventing water from draining) and the dishwasher wasn't working. To their credit, the rental agency sent maintenance promptly the next morning and they made all the repairs quickly, which we appreciated very much - they were kind and capable. Just wasn't a great first impression. Also, the cleaning people missed a few things like clothing tags from prior guests all over the closet, crumbs on the couch/kitchen table... but after seeing what spring break looks like on Port A (not a family friendly time on the beach!), I'm sure they have their work cut out for them.
Things to note for your stay: bring everything. The rental agency did provide a list of things to bring which I was thankful for, but also bring counter spray, dishwashing soap, tissues, etc. The kitchen is fairly well stocked.
The driveway parking fits two cars, not four (unless you're driving four tiny smart cars). If you need to bring more than two cars, you'll need to inquire about where to park since it says street parking isn't permitted.
