Despite the pouring rain in Milan that day resulting in limited time on the terrace, our guide, Paola R, gave us a wonderful tour. She is extremely knowledgeable and friendly. It was wasn't her fault that it was raining. She did take us up, but Mother Nature just wouldn't cooperate. I have visited the Duomo in the past, but this was my first tour and it was the best. I thank Paola for doing her very best under not so good circumstances. I highly recommend this tour.
