Yep, it's just across from the Sheraton and Hilton Doubletree on Jumeirah Beach (although Hawthorn is not directly on the beach).
Hundreds of reasonably priced restaurants on your doorstep, public transport (Dubai Tram which links to the Dubai Metro) within walking distance.
Only downside is the traffic on weekends and evenings (6-8pm) so avoid coming and going in taxis around then if at all possible.
