I really loved this apartment. It had everything I needed: two bedrooms, a washing machine, a nice shower and super-fast wifi. The location is absolutely perfect: in the middle of Cuatro Caminos -- a nice and lively neighbourhood, but the apartment is very calm. You are very close to the metro station of Cuatro Caminos, with three lines. Also, there are many buses leaving close to the apartment. By metro, you are in the center within 15 minutes.
If you like football: you are also very close to the impressive Real Madrid stadium.
The host was always very helpful, and responded quickly to my questions and requests.
Overall, I can really recommend this apartment. I had a lovely stay for three months, also thanks to this nice apartment and the ideal location.
