We stayed here for one week in January 2019. We were very pleased with our experience.
Positives: The location of the aparment is excellent to walk anywhere in the CBD and close to the bus in case you need it. I found the aparment a bit small for two people, but my gf thought the size was perfect, so no issues there. The utensils provided for the kitchen were great, we lacked nothing during our stay. The bathroom had a good size and was quite clean. The room is great and the bed is quite comfortable. We had a late check-in and the agency offered a good solution (although a bit expensive).
For improvement: There is a lot of construction going on around the aparment, which makes access a bit inconvenient and the mornings can get noisy. The apartment has no air conditioning, so we had to make do with fans. Some of the furniture was "falling apart", but the agency indicated they would resolve this. The closet is quite small and it is full of extra items needed for longer-term stays, but our stay was short enough for this not to be a big issue. We requested a late check-out and the agency confirmed via the app, but the cleaners still arrived early, which was a bit uncomfortable.
In general: Our experience was mostly positive in the apartment. It is quite comfortable and has a great location. The support from the host agency was quite adequate and timely. We would definitely recommend it to others and would consider it for our next visit to Auckland.
