Pro:
Close to two subway stations and there is a bar under the house for having a good breakfast.
Really great panoramic view of madrid from the 20th floor of the tower.
It is a perfect accommodation for a couple, and good for groups of up to 5 people like us (3 people can sleep well on the sofa beds in the living room)
Cons:
However, the accommodation is very minimal and super standard and is still 20 minutes by underground from the center, so there is nothing to justify the price so excessive (almost 100 euros per person per night to sleep on the sofa beds!!)....really too expensive...
