Very sorry to see you have not enjoyed your stay.
You booked the room two hours before you arrived. Unfortunately it was not possible to rent the car as such short notice and we told you so immediately. We tried to help you by picking you up from the ferry and driving you across the island so you could arrange an alternative rental for the same price - you must have forgotten to mention this.
The pictures of the room are reflecting what you get for your money, you chose to book it. Blackpool is not a suburb, we are in Oneroa as shown on the map when using the Airbnb website. And as mentioned in the description is very close to everything you need in Oneroa. So there shouldn’t really be any surprises, especially while your girlfriend grew up here.
Also after leaving the room in a mess with heaters permanently on full, I am not surprised that you found ants. We have never seen the room left so trashed. But don’t worry, the room got a deep clean after your stay.
