Our family has been visiting Tybee every Labor Day for the past few years. This year we had an entire week and chose Casa de Playa for our stay. The house was absolutely perfect.
Our stay coincided with the arrival of Hurricane Idalia. We decided to ride out the storm at the property, and the owner made sure that we had flashlights and water "just in case" (she also assured us that the property was well-protected by the dunes and was not prone to flooding). The house is solidly built and didn't even creak during the 60-mph winds that occurred at the height of the storm.
The house is well-appointed: the ice maker provided as much ice as we ever needed, the screen porch was a comfortable place to relax, the beds slept wonderfully, and we had no problem streaming the opening UGA football game. There were enough beach chairs and other beach stuff; a wagon, skim/boogie boards, floats, coolers, etc. that we really didn't have to use the beach stuff we brought.
The only two issues we had were:
1. The main floor was at times very chilly and we had no way to moderate the temperature because the thermostats are locked, which we totally understand.
2. We never could get hot water in the kitchen sink.
We would (and will) definitely rent this property again in the future.
