Lovely, private self-contained granny flat at the bottom of the main house. Be aware that it is quite small which was fine for me as I was staying by myself but couples may find it a bit cramped. The flat is in a great location; the beach and local shops are a short walk away and regular buses take you straight into the heart of the CBD in 20-25 minutes even in peak hour traffic.
The street is quite narrow so if you aren't particularly confident about navigating Wellington's windy, narrow, hilly streets then I'd suggest parking on one of the side streets at the bottom of the hill and walking up the stairs to the house (great way to get fit!).
