I spent a week with dune Atlantis Bali diving centre.
Everything was really well organised: transfer from the airport, hotel booking, transfer to the diving centre etc...
Regarding the dives, no complaints at all: transfer in good conditions (boat or bus), superb diving spots, very good diving conditions.
Last but not least, a fantastic team: receptionist, Drivers, teammates, dive masters are very professional.
A very nice diving centre if you want to dive here in Bali.
