I did meet Alejandro, but his girlfriend Carmen who has been very kind to wait for me quite late to give the keys. The appartment is very nice and easy to live in, with a great location. The only caveat is that it is in the basement and even if there is a small yard, day light come from the top of the building. A nice consequence of this relatice shadow is that the appartment is not too hot, and if you're out during the day you don't see the difference. In any case a nice place to stay in Madrid.
