I want to purchase terrace tickets to take the lift to the Milano Duomo Rooftop. My Mom is 78 and she has bad knees. She can climb some steps without a problem but going down steps is not feasible for her unless there aren't too many or they're not steep where she can take her time. I've read that even if you take the lift to the rooftop, there is no lift option to go back down and you have to walk down many steps.
Around how many steps on the way down and more importantly, how steep are they? I really don't want my sweet Mom to miss out on seeing the spectacular rooftop but she would be in a world of pain if it's beyond her knees' abilities. I would appreciate feedback before I decide to buy one ticket for myself or two including her.
Also, I read that the inside of this church, while beautiful, is not unique from other churches in Italy, and if we're short on time that it's fine to skip it. What are your thoughts?
Thank you!
