We spent a week at Cayetano and Concha's apartment and could not have had a better experience! The apartment is spacious and lovely and looks exactly like the pictures. The location is also very convenient. We were able to walk or metro to pretty much all of the places we wanted to see. One of our favorite touches was a guidebook that Cayetano put together with recommendations for restaurants and places to visit in each neighborhood. I would highly recommend this apartment and will stay there again if I return to Madrid!
