First of all this is a yacht (not the newest, something more traditional), it is in the sea, it is not a 5-star hotel. Space is limited by default. However, if you are looking for a unique experience, that is spending night at a yacht in the Caribbean (they are normally located near the reefs around SE of Culebra, but due to high winds they were docked near a bay), watching the stars, hearing the ocean/sea then this is a very good choice.
The owners (Jo and Lauren -hope I am not misspelling) are very helpful and full of stories. They picked us up at one of the most popular food places on the island and waited us as we ate and walked around the town. Then they took us to the yacht with a boat.
In the end, it was a unique experience. We enjoyed it a lot. Jo asked us beforehand for our favourite breakfast and they provided us with snorkel gear for the day. Again, remember this is a yacht, it is on water but it is fun.
