The staff were incredibly kind and helpful, and overall, my stay was pleasant. Do note, though, that the walls between rooms are VERY thin - if your next door neighbor snores, or gets late night phone calls and is talking, you're going to hear it. If they have their TV on, you're going to hear it. Ask for a corner room, and I'd recommend asking for something on the second floor at least, to help with the plaza/restaurant noise from below.
There is no public elevator in the building that I could see (there was one for staff use, but accessing it also required taking the stairs), so if you have any mobility issues, this is not the hotel for you, as you have to go up some narrow, steep, and curving stairs to get to your room.
The hotel is fantastically located in the city center - the tourist office is practically right next door, and the major historical monuments and buildings are all within walking distance.
Something the hotel could do to make the rooms feel cozier would be to have a small electric kettle/coffee maker in the rooms, with a small selection of teas, instant coffee, and cocoa there. That was the one thing that I really missed.
One note: there was an unpleasant sewage smell in the lobby close to the front door - I know they mentioned construction being in the area, so this might have something to do with it, but if I were the staff, I'd have someone come and check it out, just in case there's a problem with their pipes that hasn't been discovered yet.
