Living room with two characters.
Going to be hard lighting as if naturally with little space & two characters involved in the scene.
The light doesn't need to exclusively be from the front window as the patio is at the back of the house any way and obviously, movie magic.
Same with the second set up, but there's more issues if we are filming directly in front of the window. There are blinds that could be used to add a subtle twinkle in the background (shrubbery), but we'll have to think about the temperature.
The main issue with the bedroom is that there isn't as much room. Similar issues with where the light is coming from, if warm/night, can be used more effectively with the use of the practicals in the room plus obviously emphasis on warm hues/additional lights etc.
