My sister and I only stayed in Maria Elena's apartment for one night, but we enjoyed our stay. It is literally a few steps away from a metro and bus stop, making it easy to get around. There is a bakery right next door which is also a plus! As for the apartment, it was very clean, spacious and had amazing A/C which was wonderful after spending hours out in the hot Madrid sun. It also has many of the amenities that you would need and access to a kitchen. Maria Elena was also a good host and answered all of my inquiries very quickly. I would recommend this Airbnb!
