Fernando was the best host ever ! He is very friendly, he cares a lot about the well being of his guests.
The appartment (even after all that happend before he could rent it ! ;) ) is super cute, very clean, and the location amazing : we walked from the appartment to everywhere in the city, and its also very close from the subway if you're too tired to walk.
Also you can ask anything to Fernando, he will be happy to answer you about things to do in Madrid for example.
