Sandra and Mark offer a fabulous environment for dogs. The terrazzo flooring is impervious to just about anything, the yard is large and awesome, and there's a dog park a stone's throw away.
The accommodations for humans are pretty sweet too. Amazingly comfy beds (pillows, not so much, so you might want to bring your own). Nice set-up for private spaces. Essentially having two master bedrooms is great. Our family comprises three humans and four human-sized dogs. The space was perfect for us. (Though the property is advertised to accommodate up to six people, I think four really is the max.)
A few housekeeping notes: bring your own coffee, condiments, and cleaning supplies. Previous guests have graciously donated food items, but don't count on it. Do not put the knives in the dishwasher. We found them rusty and cleaned them the best we could, but they should be hand-washed. Do not put the lovely blue plates in the dishwasher as they are not dishwasher safe. The dryer is rather truculent, so give it some time. If you want to do some serious cooking, bring an extra pot. While the cookware is great, there's not enough of it to make both spaghetti sauce and spaghetti.
The beach is close, and there are towels, chairs, a brelly, and sunscreen, so you will not need to bring those items. That said, if yoiu are concerned about COVID, you may want to eschew the beach. I went one day. People were not wearing masks, filling water bottles from community water fountains, and congregating close together. Or, go at the end of the day when the beach is less crowded.
All in all, though, a great little vacation house! Enjoy!
