Tufo is cute! :)
The boat is lovely, we stayed there only for 1 night in january, but we would have loved to stay longer. Pedro was a very friendly and welcoming host who gave us valuable tips about Lisbon and Portugal. The marina has a vintage flair and is rather quiet, or at least it was so during our wintertime stay. You can hear the bridge roar in the distance, and you can hear some of the airplanes going to the airport - we didn't mind, and we slept very good. From the boat, you can take a short walk to the bridge, or even a longer walk to Belem (which we did) along the Tejo river - highly recommendable (it was raining and we got soaking wet, but it was worth it).
We would love to stay there again the next time we come to Lisbon!
