Xu was deeply impressed by the comfortable apartments and houses she stayed at and the nice hosts she met during her wedding trip to Europe in the summer of 2015.

She made up her mind to do the same thing once she returned to Shanghai and renovated her own house, inspired by the former French Concession in downtown Shanghai.

"I carefully look over a building's architecture, its style, community, facilities and even the stores around it," Xu said.

It cost between 10,000 yuan ($1,530) and 30,000 yuan to refurbish her place to her satisfaction.

"From time to time, tenants show their appreciation for some of the ingenuity that I put into the room, some of which is quite trivial," she said.

"But it gives me pride."

The growing preference for designer hotel and houses rather than star-rated or economy hotel rooms has posed an upgrade challenge for the hospitality sector.

"The middle-ranged hotels are facing potential crisis as the economy motels are no longer good enough to meet the demands of the young middle class, "said Yelv Yin, founder of Atour Group, a premier hotel brand targeting the younger generation.

Yin was one of the co-founders of Hanting and Home Inns, two popular economy hotels in China.

In 2013 Atour launched its first hotel in Xi'an, which had rooms decorated with award-winning photographs from around the world. Photography and travel lovers can experience something of being on the road in their rooms.

Over the years the group has expanded to many cities, growing its portfolio to over 100 hotels, all with different themes.

"To live in a hotel does not mean just staying somewhere else, but it's part of your life experience," Yelv added.
