My wife and I stayed at Sara's place for 30 days.
Our flight to Madrid landed pretty late, at around midnight, and she welcomed us pretty kindly.
Sara also provided us with a lot of recommendations for our stay, along with some info regarding the city and its transportation.
The apartment is located in a quiet place near a metro station which is about 7 mins away from the center.
In addition, we found the photos pretty representative to the actual apartment.
