I will second this. I grew up in an old row-home in a town not far from Philadelphia. I have very vivid memories of laying on my bed at night sweating, box fan in the window set to "High" and just roasting. My father was in sales and would go on trips from time to time. I'd always hope for him to go during one of the heat spells because my mom would then let us sleep in their room which had an old window air conditioner. In a detached house, you can at least get cross-currents going from whichever way the wind blows. But in a row-home, you are boxed in. Not to mention the fact that all the things in a city seem radiate heat: pavement, cars, trucks, the laundromat across the street, etc... When my parents finally had enough money to move to the suburbs we got a brand new house with central A/C. I think it was 90+ degrees the day we moved in. I slept like a baby in the middle of the summer for the first time in my life. It was way more magical than any tech toy I've ever gotten since.
