This tends to be a bigger problem on weekends when staffing may be extremely short handed. Look all around the rooms visited for effective housekeeping. Look behind doors, under beds, and check dusting on high areas to see what is getting missed. Dirt tends to become obvious when not tended too properly. Umbrellas for outside courtyard tables tend to be missing or not available for warmer days when residents wish to sit for a while outdoors.
Most elders do prefer shade to direct sunlight.
This gets back to review of the courtyard and other outside areas. Residents use handrails frequently to get up and down hallways. No one likes to touch dirt or someone else's trash. Touch and pay attention to handrails as you initially tour each candidate facility. Towels, washcloths, and sheets may be too rough for resident's skin.
