Yes I do believe they have disabled rooms, you would need to check direct with the hotel.
I don't know, we didn't stay there we only went for a meal which was fabulous
They do have disabled rooms as at the time of our stay there was a lady there in a wheelchair and she was able to access her room okay and also the bar and restaurant.
I thought it seemed very user friendly in every area. Hope this helps.
