6/10
It is true that train+traffic noise do come true the walls, but this did not bother me too much. Ventilation of the room is not very good and it seems to be done through roof window.
The breakfast was exeptionally good compared to what I've got in e.g. Bruxelles hotels.
To summarize: average room, little noisy but too much if you use ear plugs, super good breakfast - good deal in my opinion compared to price level.
