Semiramis Hotel

Karim Rashid designed this boutique hotel in Athens's leafy northern suburb of Kifissia, and his signature day-glo palette makes most luxury hotels look like they gave up. The pool, the spa, and a rotating art collection give guests plenty of reasons to stay put, which is convenient given that Kifissia itself is a quiet, upscale suburb rather than the city center. Bring an appetite for furniture that makes you second-guess your eyes.
