I typically travel 15-20 countries each year and consider Spotted by Locals my must-have guide. Their recommendations are excellent, particularly when you tire of the standard tourist recommendations. From great dress shops in Paris to unknown former prisons in Tallinn and lovely cafes in San Francisco, they will help you feel more like a local. (Also, the app support is top notch!)
