Yes, i've been in residential treatment as well as inpatient treatment.
I've been to 2 different residential units, and both have been completely different.

The first one, you had a single room at first, and then you'd move into a 4-bed dorm with the same sex. As it was adolescent there was a school attatched and we attended that every day for a few hours. There were therapy groups and lots of handovers. And a really long community meeting that was chaired by a patient. Food was all steamplicity, we all had chores to do after dinner. We had a lounge with a tv, and then a recreational room with a computer and table tennis table.
It was helpful, but if felt like you were bullied to get better. Too many staff not doing their job properly, some people didn't get to meet with their key nurse whilst I saw mine once/twice a week. Not a very good follow up after discharge.
I didn't really have much of a choice to go there, I was transferred from staying 3 months at a private hospital, of which my mum admitted me to after finding a suicide note and pills.

The second residential treatment centre I was in was amazing. All in all, it's your choice if you go there or not. But it was my psychiatrist that wanted me admitted. They won't accept people if they don't want to go there, as its completely voluntary. You have your own room, which is upstairs. Upstairs also has a tv room, showers, baths, toilets, a small kitchen and a nursing office. Downstairs there are several therapy rooms, a kitchen, a dining room, a living room with tvs and games consoles and also a pool table. Also a music room, a gym, a computer room and a 'quiet corner'.
There are a LOT of meetings that go on in that place. An hour long community meeting every day, ward round (with every single staff member and patients), psychodrama, dance&movement therapy, art therapy. This also had a school attatched which functioned very well.
I have to admit, it was tough. A lot of things that I didn't want to face, being pressured by staff to talk about and challenge negative thoughts. The staff were harsh, but you could tell its because they wanted to help. Being all nicey nicey just made everyone think that they could do whatever they want.
You had to go home for weekends, you had money on wednesdays to use to either go out or rent movies. We went to the peak district for a week. It also helped me concour my fear of the outside. I climbed Mount Snowdon which is something I never thought i'd do.
I learnt so much from that place, and it really helped. There were times that I was screaming to leave, not talking to anyone, but 9 months of work and I was finally discharged. They also had a good follow up service, so when I was discharged, I was seeing my individual therapist from the clinic every 2 weeks until things settled back with my cmht.
So yeah

Might have been a bit long, but any questions and i'll happily answer them!
