It is one of Cornwall's best- known landmarks.
For decades the house perched 80ft high on a rocky island off the Newquay coast has been a source of fascination.
With its suspension foot-bridge as the only means of connecting it to the mainland, the house on Towan Island is a one-off.
Last year Lord and Lady Long sold the property for an estimated £1 million and it is now being offered as a holiday let through Unique Home Stays.
Re-branded "The House in The Sea" the property will be available from the summer.
During peak season in June, for six guests the price tag is £5,575 a week.
It drops to £3,975 a week for six guests out-of-season in February.
However, in November for two people only, the cost for a week in November is £1,845.
At the moment the house is undergoing a major revamp.
Claire Lay, marketing manager for Unique Home Stays, said: "There is no other beach holiday experience like it available.
"Guests will be able to hoist a flag to let everyone know they are in residence and they have their own suspension bridge gated at the mainland end to ensure complete privacy.
"I doubt anyone would seriously risk climbing up the rocks from the beach to reach the house because it's far too risky. The house has an interesting history and is totally unique."
Built in 1901, the house has seen many owners and their guests wandering around its rooms.
They include Sir Oliver Joseph Lodge, a close friend of Sherlock Holmes creator Sir Arthur Conan Doyle. Mr Lodge is remembered as the man who invented the spark plug.
