While not on the beach directly, access to the beach was simple (couple blocks walk). Even on the 4th of July weekend the portion of the beach we accessed was much less crowded than other beaches we've gone to during the same time period. Being within walking distance was hugely beneficial since parking at the access point was extremely limited.
The property itself was immaculate and well stocked with plenty of bath and beach towels, extra sheets and pillows, starter soap, paper towels, and toilet paper. The kitchen was the most well stocked we've seen, with plenty of cooking, serving, and utensils and (uncharacteristic of other places we stayed) plenty of NICE containers for leftovers.
The biggest draw for the "sassy seahorse", though, is the pool area in the back yard. Beautifully landscaped and private, the area was SO relaxing any time of day, and beautifully lit at night. Even in the heat of the day, the tiki hut with its fan was fine for dining outside. While there are certainly newer and bigger properties closer to the beach, in peaking over the fences I still feel this property had the nicest and most private of any we saw.
We would definitely go back to the Sassy Seahorse.
