Overall good unit, very clean and easy to walk to many locations throughout the city from this spot. Also great view overlooking classic Madrid facades.
One issue was when we went to pick up our keys at 4PM (which means the unit should have already been ready for the past hour) nothing was said that the cleaning lady would still be at the apartment when we arrived (unit is not on location at key pick up site). Getting to a unit that was not ready for us to enter after a long day of travel and jet lag was disappointing.
A bit of personal preference but the king bed was hard as a rock.
Really liked the unit but a wanted to note a few flaws.
