The best thing about this apartment is that you can sit on the roof and watch the entire Plaza Mayor.
The apartment is an old historical building, but it has all the modern amenities. Because it's at roof level, you need to watch out for the low beams if you are tall.
The neighborhood is lively, right in the middle of everything. Short taxi ride to Atocha, Prado, and etc.
Magui is very responsive. We had a good time in Madrid.
