Carlo is a very gracious, friendly host. He is very responsive and communicative. The moment I arrived he explained to me all the sights to see and do in Madrid. His apartment is in the BEST location you can ask for, centrally located by all the attractions (I suggest the Mercardo de San Miguel at least once). His apartment is clean and tidy and the room you get is spacious and comfortable. If I could give 10 stars I would and will be recommending to friends/family.
