Manuel was great. Very responsive and even called after everything was squared away to make sure I was comfortable with the plan. Since his boat only fit up to 10 people and we had a party of 20, he found another boat to go with us so we could take both boats up the river together with all 20 people. He took countless pictures and videos of us when we requested and even put together a short video of our experience for us as a plus.

Insider tip: ask to go up the river instead of towards the ocean--the water is so much warmer and cleaner and you can go swimming without it being too cold! Manuel was very accommodating in this regard and it has been the best water experience we've had in Porto all summer!
