Comfortably sized for two people for a few days', and enough cooking implements etc. to facilitate easy brunches before heading out sightseeing.
If I was into cooking a simple dinner, or reheating a bought meal, I could have managed that too, especially given the supermarket is very handy.
i.e. There's a fridge/freezer, full oven, a microwave, 4 plate stove top, dish drawer, pots, pans, crockery and utensils... and salt, pepper and cooking oil we used a little of.
Hop, skip and a jump to a number of access ways from The Terrace to Lambton Quay, (and reverse) which made the airporter bus highly doable with luggage, and access to the other main sights of the city by public transport, a breeze. (We also Ubered, due to tired feet, for no more than $12 to $15 from Circa Theatre and Cuba Street eateries).
Comfortable bed, good water pressure, great fan in the toilet/bathroom en suite.
The only drawback... if you're a light sleeper who doesn't get up before the motorway traffic starts... the noise does permeate the double glazing. We're used to it as we live on a busy street in Auckland, but if one hit a heat wave in Summer, the only opening windows might necessitate ear plugs...
* proviso, we were comfortable temperature wise throughout our stay, and it may be there are air conditioning options we did not need to check out. We hit a heat wave on our last central city stay over in Wellington, and it was very uncomfortable.
