I am going to write in English because I would like to give the review for everyone.
I liked this place very much. Andre is a great host and he takes care of everyone who comes to his house. The house and room were just like in pictures, it was very warm, everything was working. It is in the good location, surrounded close to metro and bus stations. There are lots of food stores and some bars around, but the area is quiet. The flat is on the top, so if you have the very heavy bag it might be hard, but it was not for me. I will recommend this flat to other friends and will definitely come in again when coming back to Madrid.
