This apartment was an amazing place to stay while visiting Madrid: it is in the center of the city, and you can walk to most major attractions. There are also tons of shops, restaurants, and stores on your doorstep, so it’s easy to find whatever you need. As others have mentioned, it is on a major and busy street, but the windows were really well soundproofed and blocked out all the noise. We also enjoyed leaving the windows open sometimes to listen to the sounds of people passing by. Inside the apartment, everything was very clean. It was also extremely convenient to have a dishwasher and washing machine/dryer. The air conditioning worked really well, too, and overall, this was one of the most professionally managed and comfortable places we have stayed.
