Practical trip tips
Dress in layers you can take on and off easily, because the city will usually feel different in the morning and after sunset.
Keep one museum or covered landmark in reserve each day so a sudden weather shift does not ruin the plan.
Leave some breathing room in the itinerary, because this is a good month to follow the mood of the city rather than rushing it.
