Staying in a boat is always a cool experience. The hosts are super quick to respond and very attentive when you need anything. The boat is located a few steps from Torre de Belem so you will be able to see it at different times of the day. It has restaurants and other commodities near by. I think it is probably a cooler experience in the spring or summer, in the winter/fall is pretty cold, and the heater is not large/strong enough to keep you warm. I think it is good for one or two people, it has everything you need and two rooms, but the space as should be expected is pretty small within the cabin.
