Blobs of psychedelic color create a unique flow of energy in this luxury boutique hotel in the northern Athenian suburb of Kiffisia. In keeping with its up-market surrounds, the Semiramis Hotel offers a high standard of design and comfort and draws a cool collection of customers including celebrities, jetsetters and fashion savvy locals. Noted for its unconventional d'cor, the entire hotel is done in acid colors, the futuristic theme honored by practical applications of technology like free wifi, DVD players, flatscreen TVs and LED Do Not Disturb signs. While the Seramis itself serves gourmet Mediterranean fare good enough to entice considerable local patronage, the neighborhood offers a healthy selection of similarly trendy restaurants and night spots. For those making day trips into Athens, the Acropolis is about a 45-minute tram ride from here.
