This apartement in the middle of the city is the perfect place to spend a few nights on a city trip! You can discover Madrid by walking because everything is so close. Also there are lots of different restaurants and shops just a few steps away.
The flat was very clean and everything worked as it should.
For opening the door you need an app on your smartphone. The system is pretty handy, but you always have to watch out, that your phone doesn’t die, cause otherwise you can‘t get into the apartment.
I would really recommend this place!!
