You say you want to “update the furniture“ but you want to keep the beds, nightstand and dresser, but you know the dark furniture is a bit much?? So, I recommend getting rid of the dark Queen Anne furniture. It does not fit in with the pool house. Get a simple upholstered or Chippendale fretwork headboard. The other bed could be painted white. Coral and white bedding would be pretty and complement the pink stucco n the main room.
