This was a really convenient stay! The place was well located for Ponsonby, which is a cool area for shopping and restaurants. We stayed during the week and didn't notice massive amounts of noise (just the usual city stuff).
The apartment is three floors up, with both stairs and a lift (there are three steps up from the entrance to reach the lift). It has a nice little balcony with some views out over the hills in the distance.
The apartment was very clean and pretty well maintained. Absolute basics- towels, crockery for four people, shower gel, toilet roll etc- are provided, so you shouldn't need to get anything additional. It probably would be a bit challenging to cater for four people if cooking all your own meals, but it was a spot-on base to explore the city.
Beds were comfortable, and two bathrooms was also incredibly handy! Parking is in a lot nearby to the building (perhaps 20 steps) and was very convenient.
