I had one and it wasn't very nice, it was very overlooked from other hospital ward windows, it had massive windows, but opening into a central area of other windows. It didn't feel private. The blinds didn't work probably. It was a purely a long narrow room, off the ward. It didn't have its on toilet or shower. Although it was next to the ward toilet and they said I had to have the door open. That was the major thing for me. I had stayed longer in the labour ward, due to a complication from birth which meant I loss use of my leg due to the epidural, so I was actually only in my room for 8 hours.
Having your own shower, toilet is so lovely, thats would be ideal.
This was just pre Covid, early 2020, so I don't know how it's changed, but I did have my two parents, my DH and my older child visit so that was the only nice bit. They did say it was only 2 visitors at once like the ward. I found the ward hard with my first, but the private room didn't feel any better. I felt very on my own and isolated, despite the door being open I was never checked on apart from the people that did the order and brought the food.
Some of my issues are more as my DH isn't good at the support bit around my births incredibly selfish and has anxiety so very tiring for him and DS needed him at home, my parents were meant to be looking after him, but it wasn't ideal. Also a midwife upset me when I left my room to find someone carrying my DD, as pressing my buzzer go not response. I think it's a general thing in maternity wards that they don't like you carrying your baby, but I couldn't stop crying after she was so rude to me. I insisted I was going to stay the night in the room, despite having had the leg issues, which slowly resolved. I had given birth late at night, so had stayed in the labour ward all night and until about lunchtime due to the leg issue.
