So you want a spacious flat within 20 minutes of Central for under 10K? The older highrises in Discovery Bay (25 min by ferry from Central-IFC) might be an option but DB is very family-oriented and may not be for everyone ... it gives you 'air' but not much in terms of 'party' ... take a look at this thread, it might give you a better perspective or do a search on threads with 'Discovery Bay'.
