The three-bed home, in Joss Gap Road, has three reception rooms and two bathrooms, and is on the market for £435,000.
According to the property website Zoopla, the ground floor abode also boasts an "attractive" garden, direct sea views and there's no forward chain.
From the outside, it really does look fit for royalty too, which might be why it has had more than 5,020 page views on Zoopla in the past 30 days.
Estate agents Miles & Barr said: "Internal viewing is essential for this Grade II-listed home, a secure three-bed apartment within electronically-gated private grounds, situated on the cliff tops of Kingsgate.
"Built around 1760, by Lord Holland, the castle is now private apartments.
"The castle was previously an upmarket hotel in the 1930s visited by stars of the stage and screen in its day and also home to several Lords down the centuries."
"Rarely available, book your viewing today," it added.
Meanwhile, the Kent property that people have looked at the most on Zoopla over the past month is a static home in Dartford.
The two-bed property has had more than 5,360 page views in the past 30 days, and 18,406 page views since it was listed.

"This is a fully managed investment, with a guaranteed net yield of 7.92-10% per year.
"We have various sites throughout the country offering a great opportunity to a hands off investor."
