If you're yearning for an aristocratic overlay to your St-Malo experience then this peaceful 18th-century mansion should do the job nicely. It has 12 high-ceilinged rooms dressed in late-19th-century style, and glorious gardens full of flowers and shade trees. Minus: some bathrooms feel a bit dated. It's a soothing escape from the St-Malo hubbub, on the edge of the village-like St-Servan quarter.
The largest rooms are suitable for families. Breakfast is €12. Rental bikes are available.
