During our stay in Dubai, we spent more than ten days at this beach, coming early in the morning and leaving at sunset.
The beach is rather clean (can definitely be improved though), fairly long, but not insanely much so I easily swam from one side to the other (jet skis a bit annoying), there's free WiFi connection, plenty of restaurants and cafes nearby, although we mostly stayed at Kevanders, Dunkin and Chickery.
The water was crystal clear, cold at the beginning but once in very pleasant, and the beach wasn't overly crowded.
Overall we had a great time and we will gladly be back once again soon.
