Small, but lots to do!
Edinburgh is a small city where most of the touristic stuff is close by each other, but there's still a good amount to do and you can spend many days there. The city's architecture is amazing, big churches, monuments, and the castle! You can walk everywhere and get decent food without much trouble. In August, there's the Fringe Festival, which turns the city into a big circus with insane amounts of people on the streets and multiple performers. Consider that when booking your trip to Edinburgh!
