Housed in a grand Belle Époque building in Monaco’s famed Place du Casino, Hôtel de Paris Monte-Carlo is legendary and considered the best (which, for Monaco standards, is certainly saying something). The Diamond Suite - Prince Rainier III Suite pays tribute to the ‘Builder Prince’ (you’ll see artwork of the prince and Grace Kelly on the walls); the two-bedroom, 8,934-sq-ft suite has a large main living room with a bar area, sitting room and library, dining room and office space. The crowning glory is the spacious terrace with heated infinity pool equipped with countercurrent swimming jets and views of Place du Casino and the glittering Mediterranean Sea. Guests of the suite are privy to a host of extras, too — from a limousine for private transfers within the Resort Monte-Carlo Société des Bains de Mer to a 90-minute in-suite spa treatment.
