I booked this apartment for a trip to Malaga, and i would definetty recommend it:
The apartment is very well located as described, it is in the heart of the centro, and near the cathedral.
It is is also very close to the main restaurants area where you can have diner and enjoy your time during the evenings.
The apartment was very clean, and had all the equipment required. I has able to easily check-in even if I arrived very late at night.
