First note: it is NOT located on the temple property. It is a house several miles away from the temple.
The bathroom is shared with a couple of other rooms— it is NOT private. The room is clean and simple. There’s a small fridge (good sized!), a desk, a bed, a tv, and two tables with lights by the bed. There’s a closet with hangers and a small balcony. It is a bright white room. The thermostat is set around 70° so if you don’t like it frosty, bring a small heater or heated blanket.
There’s a keurig and a steam iron outside of the room to share. Host is courteous and helped me carry my bag upstairs, which was very thoughtful.
