Aqua Living

Best For: Local staff; regional expertise

Aqua Living specializes in Mykonos and has its headquarters there, which means you’ll get unparalleled access to the island-based staff. The 80 listings also cover Rhodes, Santorini, and Tinos.

What We Love: The company’s own catering service, Aquafusion (mykonoschefs.com), ensures a stellar roster of private chefs for its villas.

Standout: The five-bedroom, Cycladic-style Magic Garden, in Mykonos, whose entire second floor is dedicated to the master bedroom and its terrace ($18,900 a week).

What’s Next: Villas in Mykonos’s sister islands of Antiparos and Paros. 44-207/060-6244; mykonosvillas.com.

White Key Villas

Best For: Superb locations; local staff

The Athens-based owners focus only on properties they believe are in prime destinations, from the golden beaches of Halkidiki to cosmopolitan Santorini. All 81 properties are beachfront or have sea views.

What We Love: A concierge is always available, and on-site requests are encouraged (a fully stocked fridge, personal-training sessions, private security detail—you name it).

Standout: Villa Jade, a minimalist villa with five bedrooms on its own small bay in Kardamili ($23,100 a week). 30-210/721-5530; whitekeyvillas.com.
