We really enjoyed staying in Ven's place - it's in a great location and is near lots of great shops and restaurants, plus it's walking distance to bus stops into downtown LA and central Santa Monica. The actual room is lovely and airy, and we found it very comfortable.
You are in a room which is part of the house, so expect to hear some noise from members of the family walking/talking above you - you're not removed from the house itself. Also, make sure you check when street cleaning is, if you take a car - we didn't realise that street cleaning was a thing so we got a $50 ticket!
All in all a great stay - we were comfortable and felt safe. We also came home to banana muffins one evening which was a really nice touch :)
