Maria was an extremely friendly and welcoming host who was always available to answer any questions we had about the apartment or Madrid. The apartment itself was very nice and clean and the room was very spacious as well.
The location of the apartment is excellent, with numerous restaurants just outside the apartment, as well as being only a 3 minute walk to Puerta del Sol, and easy walking distance to many other tourist sites such as the royal palace.
I would highly recommend staying in one of Maria's rooms as she was a great host, the apartment was very nice and with the location it was great value for money. I would definitely stay here again if I return to Madrid.
