Rome
you should have no problem in rome.. one of the nicest cities i have ever been to. You will find members of the local consabulary on every corner virtually so felt very safe. they do say keep hold of your bag s etc when near a road cause the theives ride scooters.
one tip when crossing a road stand next to a local and just go when they do...the drivers tend to stop for them but not tourists
another tip never pay for a guided tour at any of the sites of interest. if you just go there and listen you will soon be able to join a free tour given by archeology and art students in the city in english. they give a free tour and then try to sell you tickets to a tour at another site. i soon learnt that when you go on to that other site (and you can walk to most of them) there will be plenty of other free tours there as well. All of them we did were excellent. Do not miss the pantheon.
have a good trip
