I had assumed that Lisbon would be quite safe. I'm not sure why, but I just assumed that it would be. Maybe it's partly that being a native Londoner I am used to having a knife held to my wrist at 4 o'clock in the afternoon on the train home, or coming home to hear that somebody has been stabbed to death in the local fried chicken shop. I know that Lisbon is plagued by graffiti, but it never occurred to me that it wasn't safe. However, I just read a review on this site which says, "IN FACT I WOULD STATE THAT IN MY OPINION IT IS A DANGEROUS AND VIOLENT CITY AND WE TRAVEL A GOOD DEAL, you have been warned" (capitals in original). How dangerous and violent is it? I am travelling with my partner. Normally we would stick together on holiday, but occasionally we might go our separate ways. Is it safe for a 20-something-year-old woman with typical Slavic blonde hair and good looks to wander around this "dangerous and violent city" alone? Is it safe for me to wander around alone? As I say, here in London I am used to having a knife drawn on me or being beaten around the head with a length of metal tubing, so my threshold for danger and violence is fairly high.
