H Bonaire is a short walk to the MTR, although the exit is pretty far from the platform itself, I'm sure you'll manage to walk it.
The area is very local: butcher, supermarket, clothing shops, no bars. The mall at South Horizon is just a station away if you need more shopping choices. Wong Chuk Hang, an upcoming arty area (by HK standards) is only 1 stop in the other direction, there are more and more offices popping up there and you might get a better western style restaurant choice.
In terms of commuting, the transfer at Admiralty isn't that long, still much shorter than the walk between Tung Chung and Island Lines at Central. However getting on a train towards Tsuen Wan may be problematic at times.
IMO it's a nice and rather quiet area and since Hong Kong is Hong Kong, if you want to go somewhere for a meal or to meet friends, it'll never be far.
