Irene was a wonderful host. She wasn't in city, but her friend gave us the keys without any problems. Irene left us detailed instructions and gave us a lot of information that was very useful.
She was always available and answered any of our question. The apartment was clean, had everything, what you needed, comfortable for two. The place is great, close to the metro station, bus stop, supermarket, cafes and other shops, we had no problems at all.
We had a wonderful time in Madrid. Would definitely recommend.
