I was with a friend who used a large scooter. This room was very large and comfortable with the scooter in it. Plenty of room to move around and the bathroom was very large and the shower was great.
One gripe I would have is the bed. The person I was with has problems with her knees and cannot get up from a low bed. This bed was so low, it was unbelievable. The steward ended up putting an extra cusion of some sort on the sofa and she had to sleep there. It was sad that she was uncomfortable on this sofa when it's supposed to be a disabled room.
The only other gripe I would have about the room is that it is the last room at the back of the ship. Trying to get a scooter or wheelchair down the corridor, especially when full of suitcases or cleaning carts was quite difficult. It's a strange place to have a disabled room.
