I will start from the Host:
Luis are very helpful guy who inform you about everything and he organized every necessary things for you.
I feel very great and very comfortable with his assists. This is the first time I saw something like this! I highly recommend Luis.
The place was very neat and clean, as described and very well located.
For me, the most important thing is that the metro and 24-hour shop (Carrefour) were close (250m from the apartment).
