I had an excellent week in Madrid. Miguel's apartment is located perfectly as I could walk wherever I wanted to go, including the well known musea. The airport shuttle bus arrives and departs at the plaza Cibeles, which is only a 5 minutes walk.
The studio is equipped with anything you need. As it was very hot weather the AC was helpful in the bedroom but was only needed for a period of time before sleeping. The street is quiet and the neighborhood safe and enjoyable. Even a bike renting place is nearby within Calle Jardines. I would recommend anyone to rent this apartment and I shall definitely come back myself as Madrid & surroundings have ample things to visit & enjoy.
