I do agree with the previous responders about the continued safety there. I visit about 5 times a year. Some ex pats friends living there have warned me of a new attempt at extortion, coming from taxi drivers. To be safe, if a taxi driver uses his/her cell phone for an incoming/outgoing call, demand that he/she disconnect the call immediately, and if he/she refuses, demand to get out of the car. While my friends are a bit protective, and I have never felt threatened in Lima, there were reports on the news (while I was there) of kidnapped tourists in Lima from taxi drivers.
