It should be ok ~ the class including accommodation should at least have a clean hotel or local training base and accommodate two people.

I have stayed in two kinds of hotels here. The hotel is an ordinary standard room with a TV and no computer, and it is cleaned every day. There is also a base, which is my own house, living in a lovely bunk bed, very clean, without TV and computer.

Maybe I care more about the teacher's teaching. I think it's enough to lead an honest and clean life and have a like-minded roommate to spend the final sprint with.
