I've only been to one, the same one several times. It's a well-regarded one in my country.
They have their own daily structure and they encourage you to follow it. Some things they were more lenient with than others. They were more insistent when it came to meals, meds and going to sleep/waking up. Breakfast was at 8:00, lunch at 12:00, dinner at 16:00, evening meal (some fruit, a sandwich, cereal or the like) at 19:00. They'd usually give the evening medication during or soon after the evening meal. By 22:00, they got everyone to go to bed. They'd usually come to wake you up at 7:00, but they'd let you stay in bed if you were still too tired, but try again right before 8:00 for breakfast. The first day of my first visit, which was after my first ctb attempt, I got there at 5am and they let me sleep undisturbed. If I recall correctly, they let me have my own room for the first week or so, then had me share rooms due to lack of space.
You were allowed to go out for walks if you let them know. Depending on how much they trusted you to be on your own, the walks could be anything from 20 minutes to a couple hours. They'd mark when you should be back by on a whiteboard, and if you were very overdue, they'd call the police. They also organized group walks with other patients and some of the staff twice a day, at 10:00 and 14:00. You were not forced to participate in them, but they would ask you to come everytime. There were group therapy sessions every day as well. They'd usually be very insistent that you try it, and if you felt it's not for you after trying it, they'd leave you alone about it. Every now and then they'd come ask if I wanted to join again, once a few days had passed, but they'd be quick to accept it if I said no.
In this place, you were allowed to have your cell phone, a laptop, a tablet device and anything else that you couldn't feasibly use to harm yourself. I was allowed to bring in drawing pencils, which I found kinda surprising. The chargers had to be kept in a locked room accessible only to staff, since they argued that they could be used to strangle yourself with. You were allowed to bring it into the ward if you had a special cable though, like one of those extensible ones. The entertainment options they offered were two sets of TVs in different rooms, board games, puzzles and some creative equipment like paint and brushes.
They did not offer me much in terms of counselling or therapy, even in the ~4 weeks I spent there after my ctb attempt. The staff would come ask you if there was anything specific I needed to bring up with the doctors/psychiatrists. The regular staff on the ward would come check on you every now and then, and also made sure to let you know that you could come talk to them anytime you feel like it. Most of them were good to talk to, but it was essentially just venting for the sake of venting.
They had clothes to lend on the ward if you didn't have much to change into or if you were cold or whatever. There were also washing machines where you'd wash your own clothes. They'd clean towels, bed sheets and pillowcases.
Overall it was okay being there so long as you did what they said. It didn't really help much for my mental state or anything, and nothing really changed once I left. The only thing it was good for in my view was that you didn't have to worry about handling your daily life, it was all handled for you. All you had to do was follow their schedule. They'd let me deviate sometimes too, I think mostly because I did what they asked generally. The boredom was the biggest issue, once you've been mostly stuck in the ward with only brief periods outside each day with very little to do, it starts to grow stale. The patients who were more defiant had a worse time of it too, their outdoor time was more restricted, they'd all been stuck in the mental for longer (some of them several months), some were force-fed or forced to take their medications. In some cases it was necessary, others it was more questionable.
