Congrats on your first batch. You can bottle it one the bubbles have stopped and the gravity is not going down. I usually check mine after the bubbling had stopped and the gravity has been the same (1.00) for 4 to 7 days. I check it and then seal everything up and check again in a few days. When the gravity is the same at each reading, then I bottle. With the EC 1118 yeast, you are going to get a very dry cider and might want to back sweeten with a non fermentable sweetener before you bottle. But I would taste some first to make sure it is the way you want it to taste.
