One week experience

Related to the housing, I can only express my gratitude to my host family. The communication went great, was easy to find, located in a beautiful place of shanghai, close to parks, and 1hr from school.
Related to school, the teachers were really nice. I took besides the group classes, individual clases, and it was worthy, more tailored to my interests ( talk and reading Hanzi)
Of course in one week you cannot expect much, but I have a pretty good conversational base.
The group classes are nice, but I would highly recommend the extra 1 to 1, to those that want to take it seriously.
If you go just for fun, the group is OK.
If you take it seriously and as an investment in your education, take 1 to 1 too.
