This is a very nice hotel which has not got any special barrier in it. When I went there I used the room and breakfast room at the third stage which was good but I did not see the dining room. So I do not have information about the dining room.
The entrance has a very small step where you can maybe need a bit of help, just a little bit. Then you have a ramp after a difficult curve (see the picture) but you will do it. A very good help would be to cut the corner of the first step.
The room is really big and it has got three beds which is great. I have had problems to find room with two beds many times in different hotels.
The bathroom is really big, you may have problems if you can not use bathtubs because you need shower pan (shower tray). They have a plastic chair to put on the bathtub, ask for it before making your reservation.
As I said the room for breakfast was good!
