A Sydney family has been reunited with their beloved Teddy bear, after accidentally leaving him behind at a Canberra hotel.

But this was not before the teddy took an impromptu tour around the capital.

Teddy's weekend romp was captured by a helpful hotel concierge, who returned the soft toy, along with photos of his adventures, to the worried family by post.

Teddy was accidently left behind at a Canberra hotel earlier this month, to the devastation of young owners, Archie, 6, and Oscar, 3.

Mother, Margie Simpson-Lee said the soft toy had been accidently caught in bed linen in the hotel room and the family did not realise they had forgotten the toy until they had driven well outside of Canberra.

But thanks to a quick-thinking concierge who located the toy, Teddy was returned to the family in the most unexpected of ways.

"He returned it to us with photos in a little envelope with great messages on the back," Ms Simpson-Lee said.

"The boys were very upset and wanted to get Teddy back.

"[But when he arrived] they were so excited, they said: 'Teddy's home, Teddy's back!'"

Before posting the toy back to Sydney, chief concierge at Hotel Realm, Robbie Allen, spent his weekend showing Teddy the local sights.

Mr Allen took him to New and Old Parliament House, Mount Ainslie lookout, Lake Burley Griffin and Floriade.

He also wrote a series of captions back of the images, one reading: "With my few extra days in Canberra, I decided to have a look around."

Ms Simpson-Lee said her sons were in hysterics when they saw the photos.

"I was showing the six-year-old, because he could understand the message, and he was just laughing out loud and my three-year-old was just enjoying seeing the photos of Teddy," she said.

She said Mr Allen had gone "above and beyond" to return the family toy.

"It is good to see in this serious world, people are still thinking about the small things and having fun," Ms Simpson-Lee said.

"I remember Robbie was being kind to the boys during the stay so I think he remembered them and it sort of resonated, and clearly he has just got a kind heart with a good sense of humour."

Mr Allen said he got the idea from French film Amélie, where the protagonist sends her father's gnome on a trip around the world and documents his trip with a series of photos.

Mr Allen said it was not a publicity stunt, he simply wanted to do something special for the kids.

"They were really lovely guests, I checked them in, and when I found out it was theirs I just wanted to make sure that it got back safely," he told the ABC.

"These sorts of things are obviously more special than your everyday phone charger that gets left behind."
