Pros:
Comfortable bed and pillows, good hair dyer, good shower, good noise insulation from the street.
Cons:
Overpriced. The studio is small and exposed. Even though the view is beautiful you gotta close the curtains to protect your privacy because you're just in front of the Plaza Mayor. You can hear noise from within the building early in the morning, no welcome details besides of bottle of wine and bad quality coffee capsules.
I doubt we would try to repeat. For a fraction of their price you can stay in one of the best hotels in town and be able to park there. You find it in G also by the name of suite Valentine.
