Fernando's space is great for anyone passing through Madrid. The location can't be beaten and the apartment has everything you need. One thing to note is that the apartment is on the fourth floor and does not have an elevator, which means climbing a lot of stairs regularly which is especially tough if you have lots of luggage or are unable to walk that many stairs. Also, the apartment doesn't really have great AC, which makes it very hot (I was in there in August). The AC unit it does have is directional and very very loud. I had no issues with the split apartment setup. I heard no noise from neighbors during my stay. The apartment also gets a good amount of light. As I said, for 1 or 2 people passing through Madrid, I think it's a great option.
