My only negative comment about the hotel is that I forgot to check if it had an elevator, and it doesn't. My own fault for 'assuming'. However, the nice man at check-in carried my very heavy bag for me up the 3 flights of medieval winding stairs, and the nice young girl on check-out did the same. (I think my bag weighed more than she did!!)
Aside from that, the location was great, on a tiny cobblestone alley with lots of interesting shops and restaurants nearby. And the room was very conveniently appointed, with large screen tv and air-conditioning (it was 20 degrees warmer than usual at this time of year). I only wish I had been staying more than one night to have been able to explore more of Liege.
