Ok, although I cannot be 100% sure what the floorplan of the house is, it is very very similar looking to the neighborhood I am familiar with on the other side of LA- looks and year built.
If you enter the front door you will be in an open entryway.All these directions will be from standing in the front entry. To the left there is a formal living room. This is that front window. Towards the back of that open formal room, in the back left of that house (if you are facing it) is the formal dining room. In front of you is a kitchen and casual eating area. In the back of the house, right corner is an informal living room. So along the back wall, the informal living opens to the kitchen which opens to the formal dining. There is a staircase that goes up from the entry way.
Behind the garage, so alongside the rt house wall, is usually a powder room and a guest bedroom/office.
Upstairs there would be two bedrooms, a bath and a master bedroom with an ensuite bathroom. I have seen it with the master windows towards the back or front of the house. Usually if there are two windows above the garage, that is the two bedrooms. If it is one large window it is usually the master. The bedroom are oriented towards the right and back- so over the garage, guest, informal living room and kitchen.
Like I said, I can't be sure but that is what I think.
I also just looked at realtor.com to see if a similar house is for sale in that neighborhood, but nothing currently.
