Reccomendations for yoga?

My bf and I just moved back in with my parents and they're both retired. There is never a moment of peace or calmness in this house. And there is absolutely no room to do yoga in my bedroom! Where should I go? I did it on my balcony once but space was still somewhat limited and sometimes it's too cold or I feel uncomfortable stretching my body all around in front of my neighbors. I live in a very populated area so I wouldn't want to do it around people at the park either.

Any ideas?
