If you're planning a trip to Madrid, you can't get wrong choosing Mariola's place!
Everything is as great as displayed in the ad and I had no disappointment. The apartment is in a good and quiet neighborhood, with a quick access to the Metro to go the main place of Madrid.
Mariola is very available, quick to respond, and will give you nice tips to visit the city if you have never been there before.
I definitely recommend contacting her for a nice stay in Madrid!
