The apartment was excellent and like described. Here's a simple pros and cons list:
+ very quiet place in centre of the building
+ clean and nicely furnished
+ excellent location
+ good matresses in every bed
+ heating / cooling system (air to air heat pump), it was good for drying air during couple of rainy days/evenings (also after laundering)
+ good briefing and a very helpful host, thanks for Jose Luis
-/+ no scenery or street view (didn't bother us because it's good for noise levels also)
+excellent bathroom (+separate toilet) even though the shower cabin was somewhat small
