If you want the Belle Époque Monaco of your imagination without the theatre of the casino square, this is the hotel. The Hermitage was built between 1890 and 1896 by the architect Jean Marquet for the Société des Bains de Mer, which still owns and runs it, along with the casino and most of what surrounds it. It sits two minutes' walk behind the Hôtel de Paris, on a quiet square, with the same owner, the same standards and a noticeably calmer lobby. The winter garden under its glass dome, engineered by Gustave Eiffel's firm, is the kind of room you drift back to at the end of every day.
With 259 rooms the place is renovated in sections rather than all at once, and the section you land in decides your stay. More than forty rooms in the Prince wing were redone for summer 2026, and Pierre-Yves Rochon has been back to rework the Diamond Suites he drew in 2004, topping out at the 283 square metre Diamond Suite Princely. The rest is the catch. Older wings can feel small and dated for the price, and many rooms face the square or the inner courtyards rather than the sea. Ask which wing before you pay. Downstairs, Bar Gustave opened in May 2026 under the dome, named for Eiffel and designed by Shirine Zirak, after the old Crystal Bar was given over to L'Abysse.
The pattern in guest feedback is consistent: staff who remember names, rooms that feel classical rather than showy, and a direct internal passage to the Thermes Marins spa, which many guests treat as the real reason to stay. That is 6,600 square metres with a heated sea-water pool, thirty-seven treatment cabins and two saunas. The hotel has no pool of its own. Pavyllon, Yannick Alléno's counter restaurant off the lobby, is the rare hotel restaurant that Monaco residents book on its own merits, and holds a star in the 2026 Michelin guide. L'Abysse Monte-Carlo, Alléno with the sushi master Naoki Kikuchi, holds two. Breakfast is not automatically included and is reliably reported as an expensive extra, while the Thermes Marins pool, sauna and gym come with the room and only the treatments cost more.
In summer, entry to the Monte-Carlo Beach Club is reserved for guests here and at two sister hotels, with a free shuttle and a boat from Port Hercule. Rates roughly double then, and can triple in Grand Prix week, usually with a minimum stay attached. It suits a couple or a pair of friends who want two or three unhurried days, the harbour below them and the whole of Monte-Carlo within ten minutes on foot. If your trip is about being seen at the casino, book next door. If it is about Monaco itself, book here.
