I want to get away for a short break, probably stay in Europe as I don't want it to cost too much (flights) due to going away in September. Thinking just 3 nights and going on my own.

So where can people recommend? And any tips please, transport, food, things to do in the evening etc etc.

At the moment I'm thinking Rome as I've always wanted to visit the colleseum etc. I'd like to go somewhere where I can pretty much just walk around the sights and grab food easily.
