Maria is a great host - we came to the flat in the middle of a night and there was no problem for her and her husband to welcome us and give us a quick tour around the flat.
The flat is just as in the pictures, everything looks nice and modern.
From the flat you have about 300m. to the metro/ train, which takes you to the city centre and the airport. Also there are few shops in the neighbourhod so you can buy yourself sth. to eat and drink (you are even able to get hot churros on your way to the metro!!).
We had a great time in Madrid!! So thank you Maria for having us at your place :)
