A different way to spend a few days near Porto. Easy access into Porto via bus or train, though we took taxis/Ubers using the FreeNow app which were great value, easy to book and reliable.
Lots of cafes and restaurants within a 5-10 minute walk and Paolo's local information guide was handy. There's a beach just a few minutes walk away and you can walk quite a distance either direction along the promenades.
Paulo the host couldn't have been more helpful. He even picked us from where we dropped off our hire car and took us to the boat then showed us round the boat. He also took us into Porto on the boat one evening (150e for a 3 hour trip), definitely worthwhile.
You must be prepared that being a boat there is not a lot of space and the showers and toilets (other than for an emergency night pee!) are at the marina, just a minute or two walk away.
