First off, Sergio was great to work with. Communication was prompt, he met us when promised, took the time to go over things at the apartment, and responded quickly to a question I had after he had left. The apartment is located a few minutes walk from both Plaza Mayor and Puerto del Sol, easy to get to the metro, shops, etc. We walked to the Prado, Royal Palace, El Rastro, etc. Great location. The apartment is beautiful; very big, high ceilings, large, open kitchen, easy to get a cross breeze with windows open. Comfortable bed (tho I always want softer pillows!); washing machine (and laundry soap) ability to dry clothes in a room open to the inner courtyard. Swimming pool was nice, tho note that there are ladders, no steps to get out. Not a problem for most people. Well equipped kitchen. The only negative comment is that, because the apartment is so centrally located, near a busy plaza, we experienced noise from late night (early morning ) revelers, primarily on the Saturday night during our stay. The apartment is one floor up, so near enough to the street that voices really carry. Most nights this wasn't a problem, and there are light and noise blocking shutters, and I carry earplugs for travel. I would stay here again, definitely.
