During my stay, Team EJ responded rapidly to address my queries on WiFi (the problem was that log-in details for two different modems had been provided to me by Team EJ) and on a noisy neighbour.
The unit (it is not actually not a 'studio apartment' as described in the AirBnB description, but a hotel room located in a hotel) is very well located in AKL CBD. The hotel reception was very helpful.
