The place is in the north of Hanoi, about half an hour to the city center. Classes are held both in the CVTD and in communities around the area. Mr. Dung takes you to class when he can but sometimes you'll have to take a bus. Food provided is good and you can also walk to the village's main street if you want to buy something. You have Monday and Tuesday off.
The classes are quite nice, some better than others. Sometimes you have a TA to help you control the students, which is helpful for the small ones.
Beds are quite uncomfortable, I couldn't get a good night of sleep most days.
