Most of the students choose to live with a host-family, as it is one of the best ways to improve your English and to discover more about English culture. You could live with a couple or a single person, with children or not, but they are always welcoming, talkative and they will be happy to share their house with you.
Homestay accommodation normally includes breakfast and dinner 7 days a week. Students have a single room or share a room with other students, as you prefer.
The residential accommodation provides comfort and security away from home and gives you the opportunity to be part of an international student community.
The universities sometimes offer their students the possibility of staying in self-catering residences or catered for residences.
A private flat or apartment will give you independence, letting you choose where you want to live and who you want to live with. But if you want to rent a place you have to sign a legally-binding agreement which you should read carefully and make sure that you understand all the details and obligations.
