Convolutional Neural Networks -- For Beginners

I want to use Image Classification to detect the category of a room in an apartment in New York City. My apartment is in a building in East Village, Manhattan and so portrays a city's box living style. It has 3 bedrooms, 1 kitchen and 1 bathroom. The pictures of these categories are what i want to feed into my Machine Learning model and want the model to predict the category of the room in that image. Upon some research, I realize we can use Convolutional Neural Networks to do this.
