If you are after that relaxed, rustic look you find in so many chic Greek hotels, the easiest way to embrace that vibe is to strip back your color palette and up the textures. Layer up whites, beiges, creams, and a touch of blue, and then bring in lots of natural textures like wood, rattan, and jute. Switch out your window treatment to something light and floaty too to really maximize any natural light.
Greek interiors are all about those natural materials, stone, and marble in particular. They add a subtle, organic texture to any space and you have so many options, both big and small, when it comes to bringing those materials into your home. If you are having a full reno, stone flooring can be found in most Greek homes, giving that lovely laid-back, rustic feel. If you're not starting any big projects and just after an update, stone pots and vases, the more rustic the better, will and a touch of Hellenistic style.
