The apartment was lovely and very secured. The owners gave you keys to both lobby and apartment doors. It had everything my girlfriend and I needed (kitchen supplies, iron and hair dryer). They were kind enough to provide us with plenty of towels. We LOVED that the apartment had a smart TV which enabled us to access Netflix, one of our favorite pastime to wind down in the evening. Although the apartment is not located in the actual Plaza Mayor, it was conveniently located close to everything we needed (lots of restaurants, banks, gyms..etc).
