Costa is a lovely resort RIGHT on the ocean and broadwalk, central to pretty much everything Hollywood Beach has to offer! I'd absolutely stay here or have friends/family stay in the future.
The units are clean and very spacious. With the thick high impact windows, you barely hear ANYTHING from outside, so it makes for a peaceful location.
My biggest advice is to purchase a weekly/monthly beach parking pass and park on Indiana or other adjacent streets to avoid the valet fee every night.
