Onefinestay is a service that gives visitors to London the chance to stay in a home with the service of a hotel while the owner is out of town. The London based startup, wich was founded in 2009, has just raised $3.7 million in Series A. The funding round was led by Index Ventures. Right now the service is only available for London. But with the new investment Onefinestay will be enabled to build unhotels across the globe. Onefinestay-guests, are invited to live like locals. During their stay they are loaned an iPhone so they can get more info about the city and make local calls. The price for a night starts at £150 and goes up to over £1,000.
