Nice location, very clean and neat, plenty of hot water and water pressure in the shower, and great air conditioning. The large sliding glass doors open onto a spacious balcony with a great view. There's a floor fan plus a ceiling fan in case you prefer that too. The bed was so comfortable I'm about to write Amy to ask what kind it is so that I can buy the same kind. Wifi was fast, so it was easy to work from there.
The studio is really well furnished - lots of bath towels, beach towels, beach chairs, books, first aid supplies(!), a lantern, scissors, an ironing board, a hair dryer, and complete kitchen supplies (there's even a blender and a burner included in the kitchenette).
For those who like fragrance: the studio is furnished with a nice coordinated set of products. If you're sensitive to fragrance you might want to ask to skip using the fancy cleaning supplies and dishsoap before your visit.
I was a bit concerned about a vacation because I wanted to avoid sharing air for COVID safety, but it was easy here -- the A/C has its own air supply, all windows and doors are pretty far from others, and there's one closed locked door in the hall between the bedroom and bathroom (that goes to the main house I assume, but I never heard any noise through it so maybe it goes to nowhere.)
Amy was super nice and responsive.
