Prince Harry was 'embarrassed' to show Meghan his Windsor cottage where he lived for six years.
The Duke said he was apprehensive about Meghan seeing two-bedroom Nottingham Cottage as she walked up the garden path in their early years of dating.
In his explosive memoir Spare, Harry wrote how he warned Meghan about the 'dolls house low' ceilings - but goes on to say he was relieved when she seemed unbothered by the humble property.
However, Harry said Meghan joked about the property being a 'frat house".
Harry writes: "I was excited to welcome Meg to my home, but also embarrassed. Nott Cott was no palace. Nott Cott was palace adjacent - that was the best you could say for it."
He also said he had no idea how "shabby" some of the furniture was until he brought Meghan to the cottage, as she was unimpressed with the bean bag and brown sofa.
Meghan and Harry lived together at the property before they eventually made the move to a newly renovated Frogmore Cottage.
The cottage, which lies within the grounds of Kensington Palace, was deemed "too small" by Meghan in their Netflix docuseries - Harry & Meghan.
Harry described how the pair made modest changes to the cottage, including buying Ikea lights and a new second-hand sofa.
Nottingham Cottage was designed by 17th Century architect Christopher Wren, who was also responsible for the south front of Hampton Court Palace, Royal Hospital Chelsea, and the Old Royal Naval College in Greenwich.
Among the allegations allegedly made in Prince Harry's tell-all memoir - he also draws a comparison between the two royal couple's former homes in a moan about how he was 'jealous' of Prince William and Kate's neighbouring setup.
He said he was stunned by the opulence of the Prince and Princess of Wales' abode, with its valuable artworks and lavish decor, leaving him "embarrassed" after spending time with them.
Viewers of Meghan and Harry's docuseries were able to get a sneak peek inside Nott Cott, including a look at the kitchen where Harry claimed in his book Spare that he was attacked by Prince William.
The kitchen has a black and white diamond patterned floor, with white kitchen units and a magnet on the dishwasher that read 'Nott Cott'.
It wasn't the space the couple had envisioned themselves living in, though, and they moaned about the conditions in the fourth episode of their docuseries.
They claimed the public assumed they were living in a massive mansion, but highlighted they were only in a "small" home neighbouring his older brother.
Harry said in the Netflix series: "As far as people were concerned we were living in a palace. [But] we were living in a cottage on palace grounds."
Meghan added: "Kensington Palace sounds very regal, of course it does, it says palace in the name. But Nottingham Cottage was so small."
And despite their comments, Rightmove told The Mirror that the average asking price for a two-bed in Kensington is a whopping £1,361,436 - with demand for that sized property up seven per cent on last year.
