根据短文理解,选择正确答案。
When people travel abroad(国外), they sometimes stay in the homes of the local people. This is a homestay.
I am living with an old English couple, in the west of London. They have a clean four-bedroom house. This is a new house. It has two bathrooms and a garden with many beautiful flowers. I have a bedroom of my own.
There are some shopping centres and a restaurant next to the house, and the house is close to an underground station. It takes about 30 minutes to take an underground to the centre of London.
I think a homestay may be a good choice for you if it is your first time to visit abroad. The local people are friendly and ready to help. If you want to celebrate the holidays with them, you will get to know more about their culture and customs.
