We had a great time in Maria's apartment. The place was really convenient and had everything we needed. Moreover, it is literally in the center 3 minutes from Plaza Mayor and 10 minutes from La puerta Del Sol. Maria was excellent host. Even if we hadn't the opportunity to meet her face to face, she was always willing to help us , with instractions and recommendations about what to do and eat. We definitely recommend Maria's apartment for your accommodation in Madrid.
