The icon is a logo of Booking. It is in the shape of a house, with half of a ribbon in the center. The ribbon has the pointed side facing down.
This is a Booking icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,100 icons, all in the same style and quality.
