Teri Ross has been getting compliments on the guest room in her Minnetonka townhouse for years — only now, they're coming from people she's never met before.

Ross is part of a growing network of Twin Cities homeowners who have discovered their inner innkeeper, using websites to market rooms in their homes to travelers much like a bed & breakfast.

The online vehicles include VRBO, FlipKey and the behemoth of the bunch, Airbnb. The business was founded six years ago by two young roommates who made their rent by charging people to sleep on air mattresses in their San Francisco loft and now boasts 600,000 listings in private homes in 34,000 cities worldwide.

Airbnb has hundreds of listings in the Twin Cities — everything from a luxury suite near Lake of the Isles to a loft in the North Loop to a couch in a modest Burnsville townhouse.

Taking in boarders is nothing new, but offering space in your home to travelers, not just in tourist hot spots like New York or San Francisco, is a more recent phenomenon. It's another twist on the "sharing economy," in which people rent out something they're not using to somebody looking for a unique experience or a bargain. Other examples are DogVacay, which connects pet owners with pet sitters, and Lyft, a car-sharing business in which regular people use their own vehicles to chauffeur passengers, which started service in Minneapolis last month.

Lyft has skirted Minneapolis' taxicab ordinances while the city determines how to regulate it. Airbnb also has come under scrutiny in some cities, such as New York, where some hosts have illegally sublet apartments they don't own but merely rent. Hotel and B & B operators in Grand Rapids, Mich., unsuccessfully sought a ban of Airbnb and other services like it last year.

Locally, Lakeville is considering changing its zoning ordinance to prohibit short-term boarding after getting complaints from some neighbors of Airbnb hosts. Ross said her neighbors in Minnetonka haven't objected, and in fact, have told her they're interested in doing it, too. Spokesmen for several other metro area communities said they have gotten no complaints and aren't considering restrictions on day-to-day stays. Some, including Lake­ville, already limit the number of nonfamily guests who can rent rooms in private homes.

Extra cash

Ross signed up as an Airbnb host the day after seeing a story about the service on "Nightline" and booked her first guest five days later. "I was shocked that it happened so soon," she said.

The recession saw more people renting out parts of their homes to make ends meet, but Ross and other Airbnb hosts say they're not driven by economic necessity. Ross says she uses the money to take ski trips around the country. Maria Verven, who runs a public relations firm out of her Golden Valley home, says she has used her Airbnb earnings to help finance the start-up of a second business.

Herb Tousley, director of the Shenehon Center for Real Estate at the University of St. Thomas, believes the economy has recovered sufficiently so that people now are renting out rooms mostly for supplemental income. "The people who were doing it as a necessity either muddled through or lost their homes," he said.

Tousley also doesn't believe services like Airbnb could put much of a dent in the hotel and motel business. A recent Boston University study found that for every 1 percent increase in Airbnb's market, traditional hotel revenue slips 0.05 percent.

"There's not a huge market for this. It takes a certain kind of person who would want to do that, stay in someone else's home. Most people want something that's more conventional, with fewer uncertainties. But there's definitely a niche for it," Tousley said.

'Playing concierge'

Like other Airbnb hosts, Steve Snider of Lakeville said he enjoys meeting new people. Snider also has stayed in Airbnb-listed homes when traveling, signing up as a host to get a discount on a room he had booked in New York.

"I figured nobody's ever going to come to Lakeville," Snider said. He didn't even bother telling his wife he had signed up and was surprised a couple of months later when he started getting inquiries.

"I've learned that there are quite a few people interested in coming to Lakeville," Snider said. He's had guests from France, India and Germany and several people visiting Carleton and St. Olaf colleges.

Snider believes he has been an advocate for Lakeville's business community by directing guests to local shops and restaurants. After discovering that a couple of guests enjoyed playing musical instruments in her home, Verven recommended places where they could hear live music. "You play host but also concierge, helping people with the ins and outs of how to enjoy the Twin Cities area," she said.

Travelers find properties on Airbnb's website by plugging in a destination city. Listings don't give street addresses but have location descriptions and photos. Once a reservation is made, Airbnb takes its cut by charging a fee to both the host and guest.

Airbnb's security measures include having guests and hosts verify identities by connecting to their social networks, scanning official IDs such as drivers' licenses or confirming other personal details. The website allows guests and hosts to review each other.

Airbnb also lets hosts decline a reservation request. Ross said she does that if it conflicts with her work or travel schedule or she doesn't feel comfortable with a request, like one from a Canadian man who said he wanted her to help him find a job. "That's not the kind of renter I want in here," she said.

The ability to choose which queries to accept was one reason LeNor Barry recently decided to list her home in Minneapolis' Ventura Village neighborhood with Airbnb. "It's not a roommate staying with you forever, but a stream of visitors from all over the world," she said.

Barry's first guests, from Des Moines, were in town about a week ago for the Arcade Fire show at Target Center. Her next booking is with a Japanese woman staying for several weeks to attend classes in Qigong, an oriental exercise and healing technique.

Barry said both hosts and guests need to be the kind of people who are open to new experiences. "You have to not see people as strangers," she said.
