It's nicely located for the train station, it's clean and there are some lovely cafes around.
However, I don't know which rooms people stayed in when they stated it was quiet. If you book here, bear in mind that the hotel is built in a courtyard shape and that in the middle is some kind of generator. If you get an outside facing room it's much quieter, but the trains run very late into the night and have ungodly brakes.
Can't fault the staff, who were very helpful in switching us away from the inner room after the first night when we couldn't sleep, though ultimately there's not a lot they can do with the building shaped like this.
But, if you're a heavy sleeper, there's probably no problem and the hotel is very convenient and safe.
