Which Floorplan and why? #2 Upstairs Unit

[Brad S.]

Here are 2 floorplans for the same proposed rental unit. I am curious as to your opinion between them. Which you like better, why, and if you have any suggestions (They are labeled B1 and B2 on bottom left). This is a 2nd floor (top flr) of a proposed 2 unit building with very limited allowable floor area (800sf gla max) and setbacks, so the shape and size of the footprint can't be altered. TIA
