The guide was excellent, her presentation in the church was well-timed to get us to the "Last Supper" ticket office at the right moment. And her comments on the painting itself, which I thought might be intrusive, weren't at all. They helped us concentrate on things we might have missed. And--for sure, 15 minutes is enough. And don't miss paying attention to the Crucifixion scene on the opposite wall, whose artist--who predated Leonardo's painting--followed traditional fresco technique, so his work still looks terrific.

The tour was excellent - our guide, Chiara, was very knowledgeable and friendly and open to questions. The tour was an interesting walk through time, with a wealth of historical facts and anecdotes - see the Last Supper in person was the final stop on the tour, and was the main reason I took the tour, but I was so glad that I did as I learned so much more about the history of Milan.

The first thing our tour guide said there were a lot of unknown facts about Leonardo and she surely delivered on her promise! The guide was super friendly, approachable, and committed to telling the story during the tour. I'd highly recommend doing this tour to get insight into the story behind the last supper painting.
