This modern micro farm in a secluded part of San Diego is for travelers who love to eat vegan. In fact, the three-bedroom home includes a garden that grows organic produce. But don't pick the veggies yourself -- a basket will be left at the back door for you and your guests to enjoy.

If you love glamping -- you know, an upscale camping experience -- stay at this rustic yet charming cabin in San Diego. The water from your outdoor shower drains directly onto plants around the home. The completely solar-powered home also has a water-free toilet called the "Lovable Loo." In the evenings, you can sit around the Mexican Chiminea fireplace while gazing at the stars.

This home in Ann Arbor, Michigan, is known for being net-zero energy thanks to solar panels and geothermal heating and air-conditioning. In fact, the homeowner hasn't paid an energy bill since 2011, according to the Airbnb listing. Just minutes away from historic Main Street, be sure to charge your electric car with the home's 240v electric vehicle charging station.

In between Hollywood Hills and Beverly Hills is a treehouse that offers 360-degree views of Los Angeles. Built in 1947, this two bedroom house was once the home of music composer Franklin Lacey. Although it may be a "treehouse," the locale still offers modern conveniences such as Apple TV and Netflix along with a fully functional kitchen.
