I think Olympic would be your best bet, but what about some new buildings around Jordon or Yau Ma Tei? Coronation Circle?
Little side rant: I really am getting frustrated with people who keep recommending SYP and Kennedy Town because they have become so expensive in the last 6 months with the MTR opening. They're the same prices, if not more than Sheung Wan. SYP has new buildings popping up every month, and you can't get anything for much less than 30k in them. The older buildings tend to not be styled very western-friendly or will have old dinky bathrooms/kitchens, and almost no views. For example, we looked at Island Crest about 2 years ago, and saw some options for around 22k. Now they're all roughly 30k. Island Crest is now unaffordable for us.
BUT if the OP wants to live somewhere with more "culture" or a less sterile feeling, then he should look around at what is available in Sheung Wan, SYP, or Kennedy Town. You can take buses like the 905 (905 goes along Des Voeux Rd. almost to Kennedy Town, 904 leaves from Kennedy Town) or buses like the 914 (maybe 930?) from Queen's Street/Connaught Rd. West bus stop to Olympic. One option in Sheung Wan might be Queen's Terrace. Should be able to get something within that budget and the location is pretty ideal for transportation/buses to Olympic. Apartment layouts are reasonable as is the overall estate. The neighborhood is interesting to walk around to see a bit of culture, and the areas around Hollywood Rd. are nice for a quiet walk.
