Airbnb, a website that allows travelers to stay in apartments instead of hotels, has acquired Localmind.

San Francisco-based Localmind allows users to ask questions and get receive answers immediately. For example, a user could ask how crowded a restaurant is and the service would respond with an answer about seat availability.

The questions are answered by users who have checked in at the place in question via Foursquare, Gowalla or Facebook Places.

Airbnb, also headquartered in San Francisco, allows users to post their apartments or other spaces as available for short term rental.

Vanture capital firms Granite Ventures, Inovia Capital and Real Ventures are among the company’s investors. Terms were not disclosed.
