I am a completely harmless, laidback middle-aged woman. If I were a t, never in a million years would I allow for an under aged minor to enter my private home for therapy without parental consent. Not just for my own protection, but for theirs, too (I'm thinking of accidents, not harmful intentions on my part).

Another red flag is there were no signs or other indications that this home was being used as his office that you could see. Seems there should have at least been a clear sign like "Ken Bendover, LSCW" on his front door. His girlfriend answering the door and watching tv in the next room has me concerned about his concern for your confidentiality rights.

Plenty of red flags here. Sure, this guy could be harmless and laid back. But you do not know that. Most concerning is you are going into a complete stranger's, unmarked home and I'm assuming no one else knows about this...except this therapist and his girlfriend. If this guy or his girlfriend have any ill intentions (conscious or unconscious) you are exceptionally easy prey for far more than the damaging consequences of bad therapy.

I'm glad you are looking for help. I know it can be a difficult process to find a good therapist. Please stay safe, be smart and not put yourself in harms way during this process. And always trust your instincts. Is there anyone like a teacher or friend's parent that can help you find a therapist?
