My Ideal Place to Live

My ideal place to live is in a small town in the countryside. My house isn’t too small and it isn’t too big. Downstairs, there is large living room with a huge, modern TV where the whole family can relax. My bedroom is upstairs and it has a great view of our beautiful garden. My ideal neighbourhood has got tree-lined streets and parks, but it also has shops and a few lively places like a cinema and a cool café to hang out with my friends. There is a baker's nearby so we can buy fresh bread every morning. The local people are friendly and don’t mind helping each other out. This is my ideal place to live because it’s a pretty, cosy place and everything you need is nearby!
