Two of London's biggest and smallest hotel rooms go head to head

Fifty pounds doesn’t buy you much hotel-room square footage in central London – barely enough room to open a suitcase, it turns out.

However, shell out an extra £19,950 and you can spend the night in your very own wing, with seven bedrooms, a library, butler – and your own postcode.

This is what travel experts from The Points Guy UK (TPG UK) reveal in a fascinating new video that takes viewers behind the keyholes of one of London’s biggest hotel rooms – and one of its smallest.

TPG UK head Nicky Kelvin spent the night in the uber-swanky £20,000-a-stay Manor House Wing at the opulent Rosewood hotel, while the site’s Jean Arnas checked into a £50-a-night double at the Z Holborn hotel.

Nicky had a better deal. Just.

The Manor House Wing is spread out over an incredible 6,000 square feet (557 square metres) and Nicky remarks on his segment as he explores that he’s getting hot walking from one end of it to the other.

He throws himself on the beds, climbs inside the humungous marble bathtub, marvels at the never-ending storage and sets plates out on the dinner table for eight.

After changing into a dress shirt and shoes, he repairs to the lounge and sips cocktails prepared by a personal barman while being serenaded by his personal keyboard player.

Meanwhile, Jean is experiencing ‘a slice of affordable luxury’, as Z Hotels describes it.

‘A very very thin slice’ might be more accurate.

‘I dare anyone to have a bad night’s sleep anywhere in the Rosewood [pictured],’ said Nicky

Nicky declared the Manor House Wing good enough to keep the fussiest of billionaires happy

The room measures just under 100 square feet – that’s 70 times smaller than the Manor House Wing. So diminutive that the head and foot of the bed lie flush to the wall.

‘There was a severe lack of storage,’ Jean told MailOnline Travel. ‘If you have a large suitcase, you may even struggle to find a spot to fully open it.’

Did he get a good night’s sleep?

‘Yes, the bed was comfy and the size of the room not visible with eyes shut!’ said Jean.

He added: ‘There was a good finish to the room. It was clean and well-appointed and incredibly reasonably priced.’

And Nicky’s verdict? He declared the Manor House Wing good enough to keep the fussiest of billionaires happy.

He said: ‘The quality and attention to detail in every corner of the room was astounding. Even the most critical of billionaires would be left satisfied.

‘There was a severe lack of storage,’ Jean told MailOnline Travel. ‘If you have a large suitcase, you may even struggle to find a spot to fully open it’

Did Jean get a good night’s sleep? ‘The bed was comfy and the size of the room not visible with eyes shut!’ he said

‘There was a surprise and delight at every turn. Toys in the kids’ room, sweets and treats everywhere you looked. The giant separate dining room fully stocked with cutlery and crockery was very novel.’

He explained that the Manor Wing could be ‘flexed up and down to go from the one-bedroom Manor House Suite to the entire seven-bedroom wing’.

‘You can select the right size to suit your entourage,’ he said. ‘Also, by affording the space a private entrance, butler and own postcode, the Rosewood has given the Manor House Wing an ingenious grandeur and gravitas that would be hard to match elsewhere.’

He added: ‘Don’t take it from me. Drake is known to stay at the Rosewood – in fact, a portrait of him hangs in the library of the Manor Suite – and in the song “Life is Good”, he raps “Manor house in Rosewood, this s**t too plush”.’

And did Nicky get a good night’s sleep?

‘Yes. I dare anyone to have a bad night’s sleep anywhere in the Rosewood.’
