A dad-of-three was left stunned after her was quoted £71,000 for a week's stay in St Ives in Cornwall.
The modern three bedroom home in the popular beauty spot was priced at £10,232 a night for a week's stay, starting from August 14.
Councillor Paul Nickerson was searching the Internet for a summer staycation for himself and his family, with three young sons aged five and under, when he came across the listing.

He searched for a property that slept five in the picturesque St Ives holiday and an average-sized house came up as a suggested booking of £71, 627 for the week, which is more than double the UK annual wage, which is £31,000.
Paul told Hull Live : "Everything I have seen is about 50% more than their normal price. We have a young family so we normally do have a UK staycation as it's easier.
"It's normally affordable for a family, but this was shocking.
"I thought it must have been a mistake, but having checked other properties, it is clear it isn't, as they're all far more."
He said holiday home owners and firms are exploiting the lack of available properties and the narrow choices people have for holidaying this year.
He said: "It's a supply and demand issue and they're exploiting it. A lot of people in the UK need and want a holiday, but many will not be able to afford them.
"I don't know anyone who can afford £71,000 for a week's holiday."
The holiday firm advertised the St Ives holiday home as a "contemporary, reverse level property ideal for families". It is near where the G7 summit of world leaders including Boris Johnson and Joe Biden, was held last month.
The holiday company said: "It is furnished to an exceptional standard and is 200m for the train to St Ives and 10 minutes to a wonderful largely deserted beach. The spacious garden is ideal for children and BBQ's."
Paul said he gave up on searching for affordable Cornwall properties and is now considering camping in East Yorkshire's South Bay in Bridlington instead.
