BWV has four single story and two 2-story GVs. All in the same area above the main store. I have stayed in both. Prefer the single-story.
The single-story has the larger combined living room, dining room, kitchen area. It also has a large laundry room near the master bath and bedroom. The second and third bedroom are on the other end of the unit.
The two-story has the stairway quickly after you enter the room and the first upstairs bedroom has a little balcony that sits over the entryway area overlooking the stairway and part of the living room. There is no laundry room to speak of. Instead, a stacked w/d sits in a small closet at the end of the upstairs walk-way next the third bedroom, where children are likely to be the occupants.. Thus, the people who usually do laundry (those staying in the master bedroom) have to walk upstairs and down the long hallway to that closet to do laundry. Moreover, the machines are loud, with the result that doing laundry at night means waking up the kids sleeping in that third bedroom.
