The weather was incredible the entirety of our holiday and the temperature was in the high 30s most days - although some days it was a little bit too hot!
If you're planning a trip to Rome, you have to visit the Colosseum, the Vatican City and the Trevi Fountain. There are lots of tours around the Colosseum and Vatican City that you can book online before you fly out. It's reasonably inexpensive and a great way to find out about the local history!
