When we were in Rome we stayed in a B&B that was literally 100m from the Colosseum. I didn't realise at the time that it sits in the centre of a roundabout.
Walking around in Rome felt like travelling through time. There's archaeological sites everywhere.
I liked Venice but not as much as Rome. It's a beautiful place. We stayed on the Grand Canal at a B&B in one of the old palaces. Venice has a certain feel to it. I'd like to go back to both again but of course I want to explore other areas before that.
