Dazzling modern art, a sparkling staircase, luscious beds, top-line bath products, and interiors that are cool/hot 21st century, thanks to a dramatic, white minimalistic lobby, and some high-style marble bathrooms—this lovely hotel on the edge of the rising-star neighborhood of Gazi has it all. The building has a neoclassic vibe, with some stunning antique touches, such as carved wood armoires and a bar lined with vintage Grecian rugs. You can see the Acropolis from seven of the rooms, especially from the gorgeous rooftop suite. The in-house restaurant is a great place for meat-lovers (note: the city's best seafood is right next door at the Michelin-starred To Varoulko). Eridanus's staff is professional and well informed and can fill you in on all the hippest happenings in town.
