Bibiana is absolutely lovely! Their daughter is incredibly adorable and their house oh so quaint. I can't say enough good things. She made me feel at home, introduced me to her family, and helped me anytime I needed anything, I didn't get to meet Gigi, but I'm sure he's just as great! As for location, you couldn't be more in the heart of the city! Room is a bit small, as it is the attic, so if you have big luggage you may need to leave it downstairs as I did. The bed was very comfy, the view from the attic is wonderful and it was a delightful first place to stay in madrid. When confused on finding it...just look for the big Calvin Klein poster in the plaza and their piso is right behind that. It served as a great landmark for me.
