JUDY WOODRUFF: Cities across the country are struggling with a shortage of housing. But there are millions of spare bedrooms. As Stephanie Leydon from PBS station WGBH explains, Boston has become a launching pad for a new technology that connects people looking for affordable rent with homeowners who have space to spare.
STEPHANIE LEYDON: Before she started her graduate program in public health, Abby Herbst got a crash course in math. There are too few apartments for too many people in Boston.
ABBY HERBST, Graduate Student: I called actually a real estate agent. And they wouldn't take me as a client, basically, I didn't have the budget for a regular place. And I was looking farther and farther outside the city.
STEPHANIE LEYDON: But she found a place just a 20-minute walk from campus in this townhouse complete with a furnished bedroom, fully equipped kitchen, and the homeowner, Brenda Atchison.
BRENDA ATCHISON, Homeowner: We fell in together very well and very smoothly.
STEPHANIE LEYDON: They met online through a home-sharing Web site called Nesterly, designed to connect two generations with compatible needs: older people who want to stay in their homes, but need help.
BRENDA ATCHISON: Twelve-foot ceilings, it's a little hard to heat in the wintertime. So a little extra doesn't hurt.
STEPHANIE LEYDON: And younger people who need a place to live. Herbst pays $650 a month, less than half the cost of studio. And she does chores.
ABBY HERBST: Like, I take out the trash, the snow shoveling.
STEPHANIE LEYDON: The home-sharing idea came to Noelle Marcus while she was living in Boston.
NOELLE MARCUS, Founder, Nesterly: It was really, really expensive to find housing while I was in graduate school there.
STEPHANIE LEYDON: She's now based here in New York.
NOELLE MARCUS: I think the average one-bedroom in New York is over $3,000.
STEPHANIE LEYDON: Maybe worse than Boston.
NOELLE MARCUS: Worse than Boston.
STEPHANIE LEYDON: She says cities across the country face an affordability crisis fueled by the same trends: a limited housing supply and an aging population of homeowners.
NOELLE MARCUS: We have had over 6,000 people reach out to us from 280 different cities around the world and tell us that they want us to expand to their city.
STEPHANIE LEYDON: Which is her goal. For now, Nesterly is available in the Boston area only. People have always rented extra rooms in their homes, right? So why do they need Nesterly?
NOELLE MARCUS: Yes. So according to AARP, 40 percent of over 45-year-olds say they're interested in renting out a room in their home, but today only 2 percent are doing it. And we think that's because the right product and the right service didn't exist.
STEPHANIE LEYDON: Nesterly offers background checks, a payment system and ongoing support. A one-time housing aide to New York's mayor, Marcus sees the platform as way to ease the housing shortage and a problem that plagues old and young alike, loneliness.
ABBY HERBST: People don't talk about it a lot. And I didn't actually anticipate it before I came to college, but, like, I had never eaten meals alone in high school before. If I feel like a little bit lonely or like I want to talk to somebody, I just come downstairs and sit in the kitchen.
STEPHANIE LEYDON: Where she and Atchison both find a perspective they couldn't get from a peer.
BRENDA ATCHISON: And you just never know. You just never know what you're going to talk about.
STEPHANIE LEYDON: That older and younger people enrich one another's lives isn't a surprise to Noelle Marcus. She moved from Boston to New York mainly to be close to her grandmother.
NOELLE MARCUS: She's 89, and she's one of my best friends.
STEPHANIE LEYDON: An inspiration for a housing innovation that helps two generations under one roof. For the PBS NewsHour, I'm Stephanie Leydon in Boston.

朱迪·伍德拉夫：全国各地的许多城市都饱受住房短缺之苦。但其实还有很多房子都处于空置状态 。根据美国公众电台PBS记者斯蒂芬妮·莱登发回的报道，波士顿新兴了一种新技术，这种技术可以联结有预期房价的买家和有闲置房屋的房东 。
艾比·赫布斯特，研究生：其实，我给一个房产中介打过电话。但他们不愿意接我这个客户，主要是因为我没有预算，连普通的价格都付不起 。所以我的预期地点就一点一点往外挪，直到挪到了城外 。
斯蒂芬妮·莱登：但她还是找到了一个住处，离市政厅的校园只有20分钟的路程。这个房子卧室配有家具，厨房用具完备 。房东名叫布伦达·艾奇逊 。
斯蒂芬妮·莱登：而年轻人也需要一个住处。艾比·赫布斯特每个月支付650美金，连工作室价格的一半都不到 。此外，她要承担家务 。
艾比·赫布斯特：人们很少谈及孤独的问题。我在上大学之前也从未想过这个问题，但这就好像我高中时代吃饭一直都有伙伴一起一样 。我每次稍微有孤独感袭来时，或者我想跟人说话的时候，我就会下楼到厨房里坐会儿 。
