My husband and I will be staying in Helsinki in late July for 2 nights, and I'm wondering if it's necessary to book a hotel with air conditioning? As a woman 'of a certain age' my ideal sleeping environment is a cool one, but if Helsinki is generally cool at night even in July then this wouldn't be an issue. (For reference, we're currently staying at the Home Hotel Katajanokka, which looks amazing--it's a former jail--but doesn't have a/c)
Many thanks, Diana
