Alfredo was the perfect host and it was so simple! He lives in the same block so that did make things a lot easier anyway.
The place is great for what we used it for (to sleep in) very comfortable and clean. The location is superb, a 3 minute walk to Plaza Mayor, 5 minutes to Sol and all relative metro stations.
It has to be noted that the apartment is on the 5 floor (102 stairs) and no lift so please bear this in mind.
