The Polish capital is busy 365 days a year—and it can be visited during any season. If you enjoy parks and trips out of the city, summer is, of course, the best time. If temperatures are hot, the fast-lane capital city seems to slow down its pace. Łódź is also a city for all seasons—it has more indoor than outdoor attractions. Hotels in Warsaw target business travelers on weekdays, and tempt tourists with lower weekend rates.
