It was a nice insight into how people lives in a big city as Madrid is. Carmen was very nice and welcoming host, I also liked to meet her cats (they were not that welcoming and did not want to cuddle with me too much :-D).
The only issue I had was the bed, which was slightly uncomfortable and was groaning every time I made a small movement (but my complains may be just due to I am spoiled).
Thank you Carmen for having me!
