This is my favorite app in my ipad. I read this page and analyzed this logo design.
Good design makes a product useful,
Airbnb is a very useful and convenient application for people who are traveling to other cities. Airbnb gives more chances to people who owns a amazing house and wants to share it with other people. Customers can choose a house they love, and contact the owner to rent. I think the most important thing is every house has unique feature, which can give travelers different experience compared to living in hotels.
Good design is unobtrusive
This logo is so simple but impressing. We can clearly see the process of logo designing. There are four different meanings in it, which are People, Place, Love and Airbnb. It only uses two colors and has no any special effects.
