Notting Hill is a real time commitment — fit it in only if it's a priority.
Allow 2–3 hrs.
Pastel houses, the Portobello Road antiques market and a leafy, well-heeled charm — very Instagrammable, especially Saturdays. Catch: the famous streets are residential (be respectful), it's pricey, and the actual market is heaving and partly tourist-tat on weekends.
