Tania's place has one bedroom and there is also a divan (two, in fact) in the living area; I was travelling with my sister and I slept here and it was very comfortable (she confirmed the same for the bed).
You are close to the central railway station, getting to the airport by bus or train is very convenient. In common with the redeveloped waterfronts of many cities, you may not find the most interesting restaurants, etc, in the immediate surrounds but the city is very navigable on foot and the Auckland transport system is extremely cheap and reliable; taxis arrive promptly.
Tania's place is spotlessly clean, the bed linen and towels lovely quality, the high ceiling and the light give a nice feel. The apartment is in a building which seems to attract a fair few visitors but nevertheless we were impressed by how quiet it was once you are inside. It was excellent value during the busy holiday period.
