Fernand has been a great host. I had not the chance the to meet him, however i was in contact with one of his friends who ensured that everything was going on well !
The apartment was great except for the heat during the summer and there is an electric fan, which is the only downside of this apartment. The bright side was that the location is exceptionnal : it is located in the middle lf all the dynamic districts of Madrid and the two nearest metros Callao and Sol are so handful ! You can get everything you want from there.
In a nutshell, great experience ! Thanks !
