This is probably as central as it gets in Malaga - the location is unbeatable. Moreover, it's a beautiful apartment, Seb is a super friendly, easygoing and helpful host and Málaga is such a lovely city. Seb also pointed us to great places to eat and explore, helped us out with baby gear for our son and even bought a new stroller when the existing one didn't fit.
We didn't use the patio as it was January and quite cold, but I imagine it's a wonderful refuge in the warm months (speaking of temperatures, be aware that the floor is really cold, so bring indoor shoes if you visit during winter - during summer, I imagine it's nice to step on something cool).
Enjoy this great city, we hope to be back!
