　　Host family accommodation, or living with host families, remains popular among language travel students for its unique advantages．These days, host families are trying to offer more in terms of quality, for they still have something to worry about．

　　Host family accommodation is often seen as the number-one choice for its advantages in language study, cultural communication and cost of living．Staying alongside host families enables students to get enough practice for the short time of their studying so that their language acquisition is likely to become faster．Living in host families also has the advantage of students of being able to spend a lot of time communicating with their “host parents”, and get to know the local way of life, people and culture．Another advantage is that host family accommodation can sometimes be the least expensive．It attracts students for it ensures them a family type of living at a low cost．

　　The advantages, however, have not prevented host families from worrying．On one hand, some host families are losing their unique selling point．The problem is that the majority of hosts in big cites, now generally single and young, have less time available for students but the selling point for host family accommodation is communication practice．On the other, 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 language travel students．
