I'll do my own research, too, of course, but:

does anyone here have any particular tips about downtown or near-downtown Wellington "extended-stay" set-ups (usually suites, apartments or motels) where a family of 3 could stay for the first few weeks of setting things up? We're looking for something budget-priced that gets cheaper according to how many weeks you agree to stay, so that you end up paying way less than a regular hotel or similar. No-frills is fine (indeed, expected!)

Any ideas considered - bus or walking distance from downtown is fine.
