The upscale chic district of Kolonaki just a few minutes from the center now has a green hotel to call its own. Periscope Hotel is trendy and design-led in a minimalist-meets-industrial-look sort of way. This once used to be an old 1950s building that has now become a secret getaway in the city. Great artwork, a fabulous breakfast, and a superb location make this gem the ultimate urban green selection. We commend the hotel on its energy-saving system, Greek Key certificate and the desire to keep things clean and simple.
