A wonderful experience! The boat is beautiful and very comfortable, with a surprisingly spacious bed and a very pleasant living space.
Fernando was wonderful with communication and very accommodating.
The toilet and shower facilities in the marina definitely aren't glamorous, but they're mostly clean and do the job.
As for location, it should be noted for those who are unfamiliar with the layout of Lisbon that the marina is quite a way from most major sights (other than the Oceanarium, which is only 10 min walk away). There are good public transport links to the city nearby, so this isn't a huge issue, and it's conveniently very close to the airport, too.
