The saleswoman at the office, the driver, and the guide were all very professional and friendly. I would give them 5 umbrellas.
However right after I walked into the first building (the cathedral), I was able to listen to about 5 items on the audio guide app before it logged me out. I was unable to log back in, and nobody answered the phones to be able to help me. I couldn’t find the tour guides anywhere (and I purchased the ticket-only option), so I couldn’t ask them. For 95% of the time I spent there, I didn’t have an audio guide which I paid for and nobody was available to help me. This part was disappointing.
