Host family accommodation means that hosts treat the student as a full member of the household, eating together with the student and sharing the common living areas with him/her. No more than three adult students or four junior students will be accommodated in host family accommodation at one time.
Host family accommodation remains popular among international students. It is the most economical and beneficial accommodation for any student. It is also the best way to practice English and learn new cultures. As a result, it is often seen as the number-one choice for its advantages in language study, cultural communication and cost of living. Staying alongside host family enables students to get enough practice during the short time of their study so that their language acquisition is likely to become faster. Living in host families, students are able to spend a lot of time communicating with their "host parents", who are often very hospitable and friendly, and get to know the local way of life, people and culture. Most host families are always ready to help students out in any situation. Often the bonds that are made between international students and their host families endure many years, and are maintained through letters and e-mails. Another advantage is that host family accommodation can sometimes be the least expensive. It attracts students as it ensures them a family type of living at a low cost.
The advantages, however, have not prevented host families from worrying. On the one hand, some host families are losing their unique selling point. One problem is that the majority of hosts in big cities, now generally single and young, have less time available for international students, but the selling point for host family accommodation is communication practice. On the other hand, students' expectations have risen. They are becoming more demanding and asking for more than ever from their accommodation, as they come mainly from high socio-economic groups in their own countries.
To get out of the difficult situation, host families are now making efforts to improve the quality of service. They are trying to make living conditions better, including broadband Internet service, private bathroom, and access to plenty of hot water for long showers. They are also providing students with structured family activities.
It is believed that host family accommodation will keep the popularity vote with international students.
