This place has an excellent location and fits a large group or family. We were 6 and had some room to spare.
We stayed in Madrid when it was very hot, but with an added ventilator , the AC unit in the living room was able to cool down the house enough.
The apartment has only one bathroom which can be challenging when traveling with such a large group.
There is a supermarket very close by as well as a coffee shop and Mercado de San Miguel just around the corner.
We had a car and were able to park it two blocks away in a parking garage and on Sunday for free on the streets.
I would recommend this place for its location, cleanliness and ease of communication.
