Personally, I think this is a must. Just last night I had the balcony open and a cool breeze filled the room with the a sweet smell of jasmine as well as providing a tingling sensation on my skin. I walked outside to follow the smell and spent the next 10 minutes just leaning over the balcony, enjoying the nighttime air and views of the Golden Gate Bridge and Marin Headlands. It was an awesome, yet brief experience.
