Santiago's apartment was perfect. He is a great host and gets back to you very quickly. We did not meet him, but his friend Carmelo let us into the apartment, gave us a tour of the apartment, and talked with us over a map of Madrid about all of the sites to see. The apartment has a lot of space, it was clean, the shower is great (clean and spacious and good water pressure), and the bed was large (definitely fine for two people) and very comfortable.
