     Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.

     What to Expect

The host will provide accommodation and meals.Rooms will be cleaned and bedcovers changed at least once a week.You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.

      Accommodation Zones

      Homestays are located in London mainly in Zones 2,3 and 4 of the transport system.Most hosts do not live in the town centre as much of central London is commercial and not residential (居住的)．Zones 3 and 4 often offer larger accommodation in a less crowded area.It is very convenient to travel in London by Underground.

    Meal Plans Available

   ◇Continental Breakfast

   ◇Breakfast and Dinner

   ◇Breakfast,Packed Lunch and Dinner

     It's important to note that few English families still provide a traditional cooked breakfast.Your accommodation includes Continental Breakfast which normally consists of fruit juice,cereal (谷物类食品),bread and tea or coffee.Cheese,fruit and cold meat are not normally part of a Continental Breakfast in England.Dinners usually  consist of meat or fish with vegetables followed by dessert,fruit and coffee.

     Friends

     If you wish to invite a friend over to visit,you must first ask your host's permission.You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.

     SelfCatering Accommodation in Private Homes

     Accommodation on a roomonly basis includes shared kitchen and bathroom facilities and often a main living room.This kind of accommodation offers an independent lifestyle and is more suitable for the longstay student.However,it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practise English at home quite as much.
