I know everyone knows San Francisco is hilly, I've known ever since I watched Full House as a child. Still it still impresses me when I'm walking down, literally down, a street.
It doesn't picture as spectacular as it looks in real life, you'll just have to visit me to see it for yourself! What also doesn't show well on a picture is how arduously steep these streets can be when you're walking uphill.
The best way to see how steep a street is to look at the front of a house and compare how much lower on side of the house goes than the other.
The first floor on the left turns into a basement on the right and the second floor on the left turns into the first floor on the right.
There are countless pretty street and house views in this city!
