This is your holiday. You'll visit Buckingham Palace, take a boat trip on the Thames and shop till you drop on Oxford Street. Some activities are pricey, others free. All are relaxing. B e savvy.
Shopping is definitely upscale, ditto for food stops.
Enjoy a browse through the Antique Passage. Their glassware is superb. And at 32 Heath Street, stop in at Louis Patisserie where tea is poured from elegant silver pots and the pastries are perfect for your soul. Bonus - a short cab ride away is the Freud Museum, where the famous doctor lived and worked after he fled Vienna in '38. The National Gallery boasts one of the largest art collections in the world.
