Yes. Ateliere Studio 102 has 2 big double windows and a blind curtain outside.
Your mom and dad didn't open the outside blind curtain. This studio is the
brightest studio among our studioes. It has the fresh air. That why I had been used it for my Aterliere.
We never used a old bed sheets but sometimes we found the hair sticked
the bed sheet even if we had carefully washed. Sorry for that if so.
There are a heater control box. They didn't push on the Bath button before
shower. your mom and dad suppose to call us by interphone whenever they
had the problems. I understand your parents generation did't have a chance to study English in China. I think This is communication problems.
