I am sorry you found the place stuffy.
I wish you had mentioned something after we spoke in person. When we were speaking outside the studio I said I would turn A/C on and then for you to let me know if the temperature needs to be further adjusted during the stay. It was cool outside and as I had mentioned when we spoke that the temperature on the main level is very different from the studio so to let me know if things needed to be further adjusted. The A/C could have been turned on higher (day or night) and it would have led to a more comfortable stay.
I hope you enjoyed the rest of your stay!
