While we did not meet Mariola in person, this apartment of hers (which seems to be part of a larger apartment that was split into three AirBNB units) has great light coming from the french doors that open out to a small balcony, with a tree outside. The apartment is smaller than it looks in the photos: don't expect to do any prep work in the kitchen, though it works well for getting a light breakfast or bringing something home to eat. The road noise at night is quite manageable, especially if you shut all the doors. It's in a great area of Madrid, residential and quiet with very close metro access and lots of shops and restaurants within a very short walk. Mariola messaged us with extensive recommendations of places to go in the area. Thanks to her for the opportunity!
