Just in case you might be packing now for your upcoming trip to Italy, pack a lot of insect/mosquito repellant! We have spent the last week fending off the nastiest, fastest little biting buggers.
The weather in southern Italy is gorgeous...conducive for leaving windows open, but this will be impossible without bug repellant to protect yourself. We were not thinking of this and therefore have ended up with more than 40 or 50 bites each, particularly at nighttime. We have left windows open during the daytime and closed at night, but obviously the mosquitoes have already entered during the daytime.
Safe travels!
