An early 20th-century mansion recently transformed into a boutique hotel, Louisa’s offers 47 suites containing everything from A/C and soundproof windows to DVDs, satellite TVs and modems – although the decorated ceilings, stunning staircase and wrought-iron banisters recall another era entirely. 

The suites come with big, modern kitchens and even though they vary in size, even the smallest are generous.The well-stocked library is ornamented with Louis XV gilt wood-panelling, while the enormous spa, with its Sanssouci Palace mural, houses a large pool, fitness area and offers a wide range of treatments. Best of all is the in-house restaurant, Balthazar’s (see page 71), well known for food every bit as stylish and refined as the surroundings.
