My daughter has spent time at one of these facilities.
It had single rooms for the patients, arts room, music room, gym amongst other features to make life as comfortable as possible.
The idea is to assess the patient in a relaxed environment to remove any fears or unnecessary responsibilities to discover what the problem is that needs addressing.
Still it is a government facility so there was one fridge for everybody's food and the clothes dryer took three hours to not dry clothes and there were maintenance issues that needed to be addressed.
Regardless we were thankful for the assistance we were given which has helped our daughter.
