If you have the opportunity (or are lucky) to rent this flat - Do it! We traveled through 7 cities from Munich to Seville and this was the BEST place. Although it is in an old building, it doesn’t have the smells and discomfort that you find when you stay in very old architecture. Michel offers a very clean and well supplied flat that is in the CENTER of everything. Many times these types of places are noisy. Not so here, and I am a light sleeper. Michel provides many nice quality towels, bedding and paper products. We have used Airbnb for years and Michel is the first person to offer to clean mid week since we stayed for six day. He truly cares about your experience in Madrid and works hard to provide the best experience possible. We will definitely stay here again when in Madrid.
