I've been to London twice and Berlin once. For the most part I felt safe in both cities, but one night getting off the tube in London on the way back to my hotel my friends and I were verbally accosted by a bunch of locals because they overheard our American accents. Being New Yorkers, we ignored them because they were a bunch of drunks being stupid, which we're pretty used to. Still, if I had been alone, or female, it would have been a lot scarier. I'd still go back though; that was one experience one night that could happen anywhere. I've been to San Francisco too, but my wife and I didn't do much wandering around at night. During the day it seemed fine everyplace we went, though there was a small alley right by our hotel that was apparently used as a toilet. Again, as a New Yorker I'm pretty familiar with being around homeless people, so what I found odd was that the leakage across the sidewalk wasn't cleaned up by the city, hotel, or shopowners around the alley first thing in the morning. Instead, it was just left there for days as far as I could tell. At the time I didn't know how common that is is SF. I didn't feel unsafe by it though, except for the threat to the cleanliness of my shoes.
