I rented a snorkel and flippers here but after 10 min in the water, I realised that I couldn t really swim with the flippers so I went back and returned them. Then I went swimming for 2 hours with just the snorkel and when I came back to pay, they said that I had to pay for the flippers too because they had to wash them . I tried reasoning with them that that s quite unfair since I only had them for 10 mins but they insisted I pay for them and the guy was quite rude about it too. So I suggest you go rent your stuff at walking street, it s half price there and the people are friendlier.
