We stayed on the boat Santa Maria 2 for three nights. And I definitely recommend this sort of accomodation in Lisboa(we were there early spring)! Host Paulo is such a kind person, he told us many lifehacks, Sent to us detailed routes for moving in Lisboa and nearby areas. Prepared some tips of visiting the city. It was so great to meet sunrise on the boat. the location is very good to take a tram abd will be on placa de commercio in less than 5 min. And the most unbelivable and wonderful moment was when Paulo surprised us with inviting into sailing tour on the boat. It was great. I will never forget this interesting expirience on Santa Maria 2.
