Fernando is incredibly repsonsive, both in communication and to your needs. His directions from the airport were perfect, allowing us to take a bus even though we were jet lagged and dazed. Upon arrival, he walked us through the apartment, had a map specially marked with necessities and items of interest. He had even provided a few staples for us (bread, jam, milk, oj) so that when we woke up at three am starving and dehydrated, we had something to sate us before falling back asleep.
The home has some beautiful antique pieces, which he told me he refinishes himself. The air con is only in the main room, but the bedroom cools down remarkably quickly. The couch is comfy, the shower is roomy, and although you can hear some of the noises from the other apartments, it's not overly intrusive. It is so close to a metro stop that traveling is easy, and you are definitely living close to the locals. Basically, it was wonderful.
My one tip is this: Don't make coffee in the apartment. That's no knock on the coffeemaker, but there is a cafe around the corner (literally) that does coffee and chocolate croissants so well that it would be a crime not patronize their shop. Overall, 5 stars all the way!
