Sergio' a boat need to be washed. He was surprised when I told him and he kindly offered to do it when I was there but I stayed only one day and I needed privacy so I declined. He said he has vacuum it by himself, the fact is that the boat needed soap and sponge. The humidity smell is very strong, I suggest a home-deodorant or something like that. We kept everything open all the time.
By the way we enjoyed Porto, the ferry boat to the center was near and we had a new experience.
