The 20 rooms occupy five floors. On each landing, two armchairs by Rietvelt and chairs by Le Corbusier, Marcel Breuer, Frank Lloyd Wright and Charles Rennie Mackintosh recall the pioneer architects of the modernist movement born at the start of the 20th century, just a few dozen years after the building housing the C2 was constructed. The light and spacious rooms, almost all different, offer comfort and refinement while retaining a certain simplicity.

The decoration is tasteful and subdued, with wood and white Corian units of a reduced height that accentuates the rooms' high ceilings. The mood is peaceful, yet warm: sections of brick wall, highly elaborate lighting and surprising carpeting designed by Guy Bargin and re-worked aerial views of Marseille that aptly replaces the C2 Hotel in its local and historical context.

The few pieces of furniture have been carefully sourced and include works by famous designers such as Antonio Citterio, Patricia Urquiola, the Campana brothers, Arne Jabobsen and Ron Arad to name just a few. On the 4th floor, the two "Exclusive" rooms each feature a sunny balcony with unhindered views of Notre-Dame de la Garde. Unforgettable breakfasts guaranteed. These two rooms also have a steam shower and a TV screen set in the wall above the bathtub for the ultimate lazy weekend. At ground-floor level, there is just one room. Impressive in size, it is in fact a former parlour.

The angels and birds painted on the panelled ceiling, the huge fireplace with its pitted mirror are vestiges of its past. As a reminder of Marseille's former days as the gateway to the East, a large four-poster bed with liana posts by the Campana brothers and a Patricia Urquiola "Mister Africa" armchair complete the furnishings
