Located on Pemba Island in Zanzibar, The Manta Resort has a remarkable jewel in its crown of luxury, an underwater sea room. It's part of an ingenious floating structure. There are three levels.
The landing deck is where the boat drops you off and the location of the lounge and bathroom. The top floor has daybeds and shades for relaxing during the day and watching the stars at night - they say you can see the Milky Way and the planets due to the lack of light pollution.
Below sea level is the submariner room, a bedroom bubble where fish glide past your window. There are even fish that have made their homes around the structure; out here, you won't be visited by other guests but by three bat fish and a trumpet fish called Nick (although I heard Nick the trumpetfish is an alcoholic, but he's fine if you catch him before 4 pm).
The room is located in a "blue hole" in the middle of a living coral reef, so it is the perfect place for diving and snorkeling enthusiasts and also people who just really like The Little Mermaid.
