Beware of Quest Nelson, they will charge your credit card after you leave without any notification for 'additional cleaning'. This was the second time my partner and I stayed at Quest Nelson (this time it was for 5 nights), we were clean and respectful of the space as we always are, and after checking out we discovered an additional unexplained charge on our credit card. After emailing reception to enquire, thinking it was an error, Quest Nelson informed us of an additional night's charge to to 'extra cleaning required', and when we requested additional information to substantiate the claim, they completely avoided any response.
Separately, my partner was involved in an accident and required crutches so we booked an accessible room. On the day he was coming out of the hospital I asked reception to inform the cleaning staff that there were a lot of items (rubbish, vacuum cleaner, rollaway bed etc) that was blocking the hallway and a potential trip hazard, and asked the hallway be clear for when we return to our room. That request was taken on board for that first day, however every subsequent day, there continued to be items in the hallway blocking easy access to the room.
Overall, I am disappointed in Quest Nelson and would recommend you avoid them as our experience has been just awful.
