All based on going in June when it was a bit busy
Spanish steps = Yawn
Trevi Fountain = A bit oh is that all
Pantheon = Ace
Colloseum = Ace
All the ruins to the west of the collseum = Ace
Piazza Novona = Pretty good with plenty going on also there is a restaurant literally at the south entrance (on the path in) which was good but then I’ve never been to a bad eating place in Italy.
Vatican stuff = PITA as the queue is massive so a very early start needed. Literally had no time as stepped on train 30 seconds before it left after dragging wife through the Cistine chapel with only a glance at the ceiling. This was the second attempt to get in but the queue was back to St Peters square and 5 across the first time.
I’d agree with pretty much all that, although we had better luck with the Vatican – definitely get there early. Best thing IMO was just wandering about, there’s something to see around every corner.
For eating, just get off the main streets – any restaurant with pictures on the menu is probably best avoided 🙂
