The apartment is in a great location, close to Plaza Mayor and easy to get to the rest of the city. It’s also very close to multiple metro stations, but you almost don’t need them since you can walk most places from the apartment. Maria was kind and offered good advice. The place is clean and perfect if you are looking from an easy and central place, especially if you will be spending your time exploring the city. I always felt safe in the area of the apartment, even at night. Definitely will stay again next time I am in Madrid!
