If you are planning a trip to Milan, take care of the tickets right away. We walked around, but we didn't get inside, as tickets could only be purchased in a month.
There is nothing special to paint here, since in this church is the very Last Supper. Compared to the Vatican Museum, the organization of the tour is simply on top, everything is comfortable, very good guides. Well, it's a little pity for the artist who painted the mural on the opposite wall: no one knows him, although he painted very well and beautifully, and the Last Supper is saved all the time from the moment of its completion.
