A so-called underwater hotel is being advertised on holiday site Tripadvisor - complete with ocean views.

But if you want to book you'll have to sink deep... the cost is advertised as £999 per night!

A spoof ad, it will allow you to try to book the one-bedroom condo/apartment in Dover that sleeps seven.

But beware, as the heading warns... "Please don't book this house. It has nothing to offer you."

Under amenities the listing says it has internet access, a microwave and... err, ocean views!

But, strangely enough, the property has had no reviews yet.
