Guy lied to me about his roommate? Is it unsafe to go at his place next time?

So I met that guy from dating app and went to his place to hook up, he told me his roommate wasn't therez but I after we hooked up he started talking to him and I went out of the room and saw him standing at his door and talking.

He didn't leave his room though and was so silent all the time that if they didn't start talking last minute, I wouldn't be able to tell there was someone in that apt except us.

The idea of someone being that close while we were doing that kinda turned me on, so I didn't make any comment about it, I just left. But I want to see him again and I'm thinking if it's safe to see him at his place again? Or should I rent something?

What are your thoughts about that?
