We rang the Quality Hotel on the way back to Blenheim after arriving, viewing and then immediately cancelling our accommodation in Picton, due to it being below expectations.
The staff member we rang was so helpful and luckily they had a room for 4 night. We arrived and met by a lovely staff member (think he was the assistant manager) and after the admin stuff we were shown to room 6, a very large corner room with king size bed. We couldn't have been happier after our last experience.
The Hotel is single story and our room was definitely the bigger of the rooms we were able to see. Car parking is free onsite and breakfast is available, but a bit pricey at $22.50 for a hot selection, however Blenheim is so close and plenty of choice is there.
The Hotel is about 1 minute off SH1 on Nelson St, and albeit on SH6 (turn right out of the hotel and keep driving and you are on SH6 and heading to Nelson.
There are no laundry facilities however for a charge they'll wash, dry and fold it for you.
We'll be staying here again if we get the chance
