Both times I gave birth at Matilda, which were great experiences, no complaints. I have not visited the maternity ward at Canossa, but we go there regularly as our doctor is the head pediatrician there. Both of my kids have been admitted to the pediatric ward at Canossa on separate occasions, so I've spent the night with them there. Based on that, I would say that the in-room facilities are similar, and the staff are just as friendly and helpful. However, there seems to be something about Matilda that makes it extra "comfortable" and "luxurious". Perhaps the view and fresh air?
