I'm very much into Italian history, culture and food, so my favourite of the cities I've visited is probably Rome. The food is gorgeous. There are so many historical landmarks and things to see and do. Everything is beautiful - even tiny back alleys often sport ornate fountains, sculptures or architecture. It's a big city, but you can walk almost anywhere. I loved almost everything about Rome.
I was in Verona for part of my honeymoon earlier this month, and that was a great experience too. It's a beautiful city, but much more understated and relaxed than Rome. There's not as much to do there, but the atmosphere is great. It was a pleasant surprise as I had been looking forward to seeing Venice on my trip much more, but Verona probably left a bigger impression.
Florence is the next city on my bucket list that I really want to see.

I actually quite like Glasgow. People seemed cool - probably the closest to the Irish mentality that I've seen in a foreign city if that makes any sense. The best concert I've ever seen live was in Glasgow, and a big part of that was the crowd. It also has by far my favourite airport that I've been to.

It felt like a small town train station. I was basically in and out in 5 minutes each way.
