Here, 답답하다 means stuffy, airless, or oppressive—the feeling you get when a room needs fresh air.
This word is also used for emotions, where it can mean frustrated, constricted, or uneasy, but in this sentence it is clearly the physical meaning: the room felt stuffy.
이/가 marks the subject, while 을/를 marks the object.
In this sentence, the room is the thing that is stuffy, so 방이 is the subject of 답답하다:
- 방이 답답하다 = The room is stuffy
If you said 방을, it would sound like the room is receiving an action, which is not what is happening here.
Both can work, but the nuance is a little different.
- 방이 너무 답답해서... focuses on the room as the thing that is stuffy.
- 방은 너무 답답해서... would make the room more of a topic, sometimes with a slight contrastive feeling, like As for the room, it was so stuffy...
In a simple sentence like this, 이/가 is very natural because it just states the condition directly.
