It's everything as advertised, the audio guide worked well, but I recommend downloading before hand because it is 100MB+ If you book the Cruise with the Cellar Tour, the process is kind of convoluted depending on what language you speak. English language cellar tours are usually in the mornings and the cruises start at 9:30, so you can realistically only book the first two time slots for both events. Also when you get your vouchers from the ice cream stand, go early enough so that you have time to walk to the Cellar and book the tour in person before you board the boat. (14 min round trip walk)

Had booked for a 11:30an trip but apparently was one boat on the hour. Would have been useful to be alerted before hand about any audio that could be provided on an app before I arrived so I could install on my phone before arriving. Otherwise the trip was around 50mins as expected.

Boat trip is nice, you can see the bridges, even though the Louis bridge is the only one being truly interesting. Audio guide is disapointing: uninteresting, too formal, lacks humor/anecdotes, waiting times filled with loud repetitive music between every voice information. Burmester porto cave visit was okay, our guide was nice, but the wine itself felt cheap, or it’s really not our taste. We found Don Pablo’s porto way better, and even tried some greater options at random restaurants.
