We stayed here for a week and had a pretty good time.
However, the photos don't show the whole picture - definitely do your detective work and decide if this is where you'd want to stay. For us, we wouldn't choose it again.
The location of this place is truly IN a grocery store parking lot. Make sure to use the bird's eye feature in Maps to understand. It is above a nail salon and restaurant called The Village. Exhaust from the fish and chips place enters the main living area if the door to the patio is open. The pictures of this listing completely omit any hints that this is in a busy parking lot. Looking back at the photos in the listing while we were there, it really seems like an intentional omission (this is only our speculation).
Also, there are a lot of stairs to navigate - it's a big part of getting around this space - up and down flights of stairs.
Otherwise, the beds were comfortable, the location is surely central, and the town of Sumner itself is super lovely
