We moved-in last November. It's been great! Chose it mainly for my kids as there are 5 pools - deep one for diving, olympic length, medium depth, calf deep for kids with slide and one other medium depth - a couple of playgrounds with swings etc. There's also 3 tennis courts, a putting green, 6 BBQ areas, et al.
I visited quite a few places before deciding on Costa. It appears more like a resort. Almost all the units I believe have a view towards the south of the ocean except for units below the 5th floor as their view is blocked by the trees in East Coast Park. It's not as hot as other places because there's no other buildings blocking it. Even if you're in the northern building towards east, the layout of the buildings captures the breezes and funnels it between the buildings.
There's a restaurant near the clubhouse, a small grocery, a salon, manicure/massage place, drycleaning service, and dvd rental place. There's a semi-private shuttle (SG$5) that picks up folks every 10 minutes starting @ ~7am to bring you to the CBD area and has return trips in the afternoon. The public bus stop is about 2 blocks away. There's another shuttle that brings folks to the Bedok MRT, as well as Parkway Parade shopping mall.
There's an underground passage way from the unit to the east coast park, where you can jog, ski, rent windsurfing eqpt, restaurants, hawker stall, rent rollerblades and bikes, etc. Definitely accessible.
In terms of tenants, it's more of a family environment. There appears to be more kids compared to the other facilities I've visited. Overall it's been a good experience. Except for the neighbor cooking dried fish 3 or 4 nights a week (haven't found out who it is yet) and having the smell come into my unit forcing me to close my windows, it's been good!
