You might think 5-star hotels are the best, but there's actually a 7-star hotel - and it's the only one in the world.
Thanks to YouTube, we get to see inside without spending tonnes of cash.
YouTuber George Mavrakis had a look around the Burj Al Arab in Dubai - known as the 'World's Only 7 Star Hotel'.
Although it was built in 1999, the hotel didn't open its doors to non-guests until 2021.

It costs over $1 billion to build and to reach it, you need a helicopter as it's on its very own private island.
Without one, you can enter by a 'heavily guarded bridge' which is how Mavrakis got in.
'Right when you enter you're met with two aquariums on either side of the lobby,' the YouTuber described. 'Each one is 250,000 litres (66,043 gallons).'
He then goes upstairs and shows around the 'world's tallest atrium' and it's breath-taking.
'Visitors can take a tour inside the Royal Suite and see the insane luxury that exists,' Mavrakis said.
To stay in the Royal Suite, you would need to fork out a whopping $25,000 a night.
The golden marble staircase inside the suite is truly one to be marvelled at as well as the 24-carat gold ceiling and walls.
Through the living room, visitors have access to a gold-plated TV and stunning views of Dubai.
Oh, and there's a private elevator that takes you straight to your room.
Fredrick, the suite's butler, described the hotel being a place of attraction for 'high profile visitors' such as Justin Bieber and Nelson Mandela
The Queen's Bedroom is equipped with a 'secret mirror' on the ceiling while the Queen's Bathroom is where royalty really comes in.
By that, I mean the taps are complete with real ruby and sapphire.
Meanwhile, the King's Room has a rotating bed that would even make Austin Powers jealous. The King's Bathroom has a toilet that opens automatically as well as a 'gold plated bidet.'
'The shower is the most insane thing I've ever seen. The entire thing is gold-plated,' he went on.
Even the observation deck is a hotspot for celebrity activities.
'Some of the coolest activities have happened here,' Mavrakis says as he shows off the golf bag Tiger Woods had when he hit a golf ball off of the deck. Not to mention the rackets used when Roger Federer and Andre Agassi played a tennis match there and an F1 car performed doughnuts on the helipad.
Finally, the biggest aquarium was saved till last, for the dining experience. Measuring 4.5 metres (14.76 feet) deep and containing 300,000 litres (79,200 gallons) of water it houses many aquatic species like batfish, butterfly fish and unicorn tang to name a few.
It's so extensive that people can scuba dive in it.
