Pro: the view is amazing, you only have to climb 300 steps (aproximativ 10 min) to get on top, the guide that is waiting for you on the top of the church is amazing (Willem is the best ever), the tickets are cheap (3€ to visit the church and 7,5€ to visit the church + climb on top of it)

Cons: the lady at the ticket booth is not friendly because me and my friends bought 4 tickets. After paying the tickets, we asked for bathroom, she said that she will get our tickets when we go back. 5 minutes later, at the tickets booth were 20 people standing in line to get tickets, we asked for our own and she told us to wait until she gets the tickets to the other people. I am finding that not ok because we should’ve got the tickets before going to bathroom, in the first place, and second, we should’ve got our tickets when we came back, not to wait after all those people when we already waited in line once.

Also, if you are claustrophobic, you should avoid the view on the church because the way to the top is pretty tight.
