Staying on a boat is cool, there's no two ways about it! The Nautilus is very cosy, extremely clean and surprisingly spaceous. The facilities are as good as any terrestrial and the whole place has a rugged-but-pretty charm. The outdoor sofas are especially unique. We didn't, but I imagine once the fire is lit that would be a lovely place for spending an evening with friends.
Highly recommended if you need to stay in the area.
