We stayed 1 night for a CERN visit, since their hostel was full. Expected a very standard hotel; the room certainly exceeded expectations. The kitchenette is very well-equipped and clean; the room has a very spacious lounge, and the bedroom is through another door, which makes a cosy space for a decent night's sleep.
No wifi in the room (though I'm told that will change from late 2012), and not a vast amount of choice for the breakfast. But these are really minor quibbles. I would certainly not hesitate to stay again.
