Whether you're staying at luxury rentals in Paris or taking a trip around the world, getting a dose of caffeine can sometimes prove to be difficult. Coffee culture is alive and well in much of Europe and has even crossed over the equator to Australia and New Zealand, where espresso drinks dubbed flat whites are as commonplace as a cup of Joe in the states.

If you can't live without a morning buzz, here are a few recommendations for the best global coffee destinations - all of which are conveniently located in major cities near many luxury vacation rentals.

Get your fix in Rome, Italy

Espresso is a staple beverage for many Italians, who take 2-ounce shots to keep their minds alert throughout the day. At Caffe Sant'Eustachio, one of the city's most famous coffee shops, you can get a taste of history as you sip your smooth and bitter jolt of energy. Located mere blocks away from the Pantheon, Caffe's water source comes from aqueducts built in 19 B.C., which espresso connoisseurs believe creates a unique quality in the shop's drinks.

Caffe is often packed to the brim with suit-clad locals stopping in for a drink before, during and after work, so be prepared to wait in line if you go at morning rush-hour times.

Philosophize in Paris

Ernest Hemingway, Albert Camus and Pablo Picasso once frequented Les Deux Magots cafe in Paris, which stands as one of the city's most famous espresso joints. Now a popular tourist destination, Les Deux Magots is a perfect place to grab a coffee and pastry while you're touring the beautiful and charming Parisian streets.

Puerto Vallarta's Oro Verde Cafe, owned by a Swedish woman named Paty, is a hidden coffee gem in the middle of a tropical paradise. This homey joint is an ideal spot to escape from the sun for a few minutes while enjoying a delicious homemade pie filled with coconut, pears, mangoes and guayaba fruits. You can also get a smooth cup of coffee or rich latte as you talk to Paty, who knows about all of the best beaches and hidden coves in the area.
