We were at Kingfish Beach Retreat for a week between Christmas and New Year. The house is well equipped with all amenities required for a comfortable stay. The owners gave us our privacy but were always available (through Harold) for questions and requests. It rained a lot during our stay and it's hard keeping two toddlers dry so we needed a hair dryer - sent a message and it was at the door in less than an hour!
The house is ideally located for day trips, plenty of places to see within an hour or two. The weather was a bit disappointing, it was cold, rainy for the most part, so didn't get to enjoy the beaches. But there's plenty to do otherwise in Gulfport and surrounding areas. We traveled with two young kids, and found lots of options that were of interest to them as well. (Lynn Meadows Discovery Center, IMMS, Gulf Coast Gators Ranch, Town Green, The Secretly Awesome Tour in Mobile AL, Day Trip to New Orleans, Pecan House, Biloxi Light House, etc) Would like to go back when the weather is warmer and sunny.
